Bangalore Kubernetes Meetup #4 and update on next community event

Last weekend  we had 4th Kubernetes Meetup in Bangalore at VMware’s office. More than 100 people signed and ~40 people showed  up. The first session was from  Akshay Mathur and Manu Dilip Shah  of A10 Networks who shared their experience on choosing  and using Kubernetes for their  product.

The next session was from Krishna Kumar and Dhilip Kumar from Huawei who talked about  managing stateful application with Kubernetes. Krishna first gave us good overview and then Dhilip showed us a demo.  He also urged participant to join Kubernetes Stateful SIG.

The last talk was from Magesh and Kumar Gaurav of VMware on using using k8s to orchestrate VMware SaaS. It was an interesting talk on which Magesh talk about some real problems his team has faced.

Some participants asked about comparing Docker Swarm, Kubernetes, Mesos Marathon and other container orchestration. We had brief  discussion about I share my last year’s LinuxCon/ContainerCon EU workshop on comparing different  container orchestrators.

We also talked about on what we should do in in the next Kubernetes meetup. We might do hands-on labs.

In the end I also shared the details about the community event we are doing in conjunction with other meetup groups like one we did few weeks back AWS, DevOps and Docker meetup groups.   In April we plan to do similar event  on Microservices and Serverless. Other than previous participants Kubernetes and Mesos & CNCF meetup group would also be joining it.

It was a good meetup. Thanks for the organisers and speakers.

AWS, DevOps and Docker Meetup

Continuing our experiment with community driven conference, this time AWS,DevOps and Docker meetup collaborated to do a combined meetup. We charged INR 100 to each participants to make sure they are really interested in coming. From the collected money we gave gifts to speakers and some prized to the participants. The meetup was hosted at Bangalore’s LinkedIn office. It was really nice venue and and everything went as expected.

AWS, DevOps and Docker Meetup - Feb'17

AWS, DevOps and Docker Meetup – Feb’17

Out of 150 participants ~140 showed up, which is really nice. Some people came from Chennai and Cochin as well. So putting a nominal fee really works :). We started almost on time. The first talk was from Neeraj Shah from Minjar Cloud. He shared his experience on how he deployed application on ECS. He mentioned the advantages of using ECS to deploy Docker based application on Cloud and why one should use it.


Next talk was on from Mohit Sethi, who talked about managing storage in containerised  environments.

Sreenivas Makam then talked about Docker 1.13 experimental features. He briefly introduced us with new features of Docker 1.13 and then focussed on experimental feature. Experimental features can enabled from stable binary only, which is a real help for anyone who wants to try out upcoming Docker features. In the end we also good discussion about Docker Stack.

We took a quick break after that and had quick intro session with all the organisers. After the break Madan shared some great tips on saving cost with AWS.

After that Shamasis shared Postman’s scaling journey with Docker and AWS Beanstalk. It was really fascinating.

In the first Flash talk Gourav Shah open-sourced  a project on creating Devops workspaces using Docker. Generally one is required to have more than one machined to try DevOps tools like Chef, Puppet Ansible etc. With this tool one can build a multi-node setup using Docker and do different labs.

The last session was from Mitesh, who showed to use Jenkins and CodeDeploy to deploy the applications on AWS.

All of the sessions were very informative, venue was host, participants were eager to learn. I think it was really good meetup.

Thanks to all the speakers and our host Bathri and Sethil at LinkedIn. Thanks to organisers for AWS and DevOps meetup group specially Mohit and Habeeb.

During the meetup some other meetup groups came forward to join us next time. We might do something around Micro-services and Serverless in April last week in the similar mode. So stay tuned 🙂

Bangalore Docker Meetup # 24

We did our first meetup for 2017 at GO-Jek’s engineering office in Bangalore. ~400 people rsvped and ~120 people came for the meetup. This is first time we tried to live-stream and record the videos. Though we could not record all the videos due to out lack of experience but still we got two complete ones, which I think is a good start. This first session was from Nishant Totla of Docker. He talked about Docker Swarm and Swarmkit.

The next session was from Saifi Khan who talked about Docker on Windows. He had no slides but demos. Somehow he had an issue with the display driver so we could not see the demo but even without any slides and demo, he engaged the audience with nicely and had very interactive Q & A session.

After Saifi, Thomas Chacko talked about Serverless Computing and Docker. He have very informative overview with some demos.

Docker serverless v1.0 from Thomas Chacko

Next was Kiran Mova form OpenEBS, who talked about Emerging storage technologies for containers.

Lastly I gave a demo on Jenkin’s Docker Plugin and how we can the Jenkins pipeline to build CI/CD environment.

Within the community we were discussing about the community driven mini-conference/larger meetup for some time, which I documented here. Lets see if we can take it forward or not.

I also shared the details about the MOOC on container technologies which my company is launching on 14th Jan’17. The first course would be on Containers Fundamentals. You can find more details here.

We plan to live-stream and record future meetups. Hope to do better next time.

Time for Community Driven Conference/Larger Meetup ?

You name the technology and you would find active meetup in Bangalore. Be it Docker, DevOps, AWS, GlusterFS, Machine Learning etc. Every meetup  group meets at-least once in every two months and share the knowledge. These days cloud, be it public or private seems to common platform for everyone and containers are slowly becoming unit of execution.  There are few conferences which are dedicated on these topics which bring people together. This idea is on similar lines but the quest is whether can we do a conference which driven by the community ?

Last year Docker and DevOps meetup group did a joint one day meetup, for which we received good feedback. By doing such a joint meetup we can extend it to mini-conference but there are few questions which arise :-

  • Who would provide the venue ?
  • What if we announce the conference, sell few tickets but don’t have enough fund to pull it off ?
  • What if we don’t find the sponsors ?
  • etc..

Can we play safe here ? May be Yes !!! With discussion with some of the other meetup organiser we thought of following:-

 

containers-and-devops-community-event-4

We’ll open-up 200 registration in the beginning and then ask people to pay 200 per ticket. 200 registrations because that is what we can accommodate in a meetup, if event does not happen. We are charging some money to make sure participant is really interested.

Once 200 people are signed up we can go to companies for sponsoring the venue. The company can pay us or directly to the venue/event management. If we don’t get the sponsorship  then we’ll just to a meetup  as usual. Whatever money we collected so far, we can give that back in prizes during the meetup.

Sounds good ?? This is just a concept now. Lets see if we can take it forward in next week or so. Do leave your comments if you suggestions/idea ?

A year on my own…

Today I completed one year of being on my own.

In 2004, after graduating from college and doing brief experiment with a startup I came to Pune, looking for a job. I failed clearing the interviews of many MNCs. In the last two and a half years of my college I spent most of my time learning Linux and Computer networks. So, I decided to narrow down my search where there is requirement of some Linux Admin work and after giving my first interview, I got the job. Anyways coming forward, I do had some plans after leaving my full time job but didn’t know what coming next. As last time Linux helped again but this time in the form of  The Linux Foundation. I got an assignment from The Linux Foundation to build a self paced course on “Cloud Infrastructure Technologies”, which got launched in June’16.

Between Dec’15 – March’16 months I also gave free containers(Docker) workshops in Bangalore, Pune, Chennai, Hyderabad and Kolkatta. At the same time I gave some paid workshops as well.

Within a month after leaving my job I realised how easy it be an employee than your own boss. One has to manage his/her time, next month’s pay check, family, health and so on without loosing the cool. After going through on my own I started to respect entrepreneurs, self employed, my local vendors, auto rickshaw drivers etc more.

Less sleep, lot of work took a toll on my body and I got struck with Bell’s Palsy in Jan’16. It was very scary to go under MRI in the middle of nigh for the checkup. It took me few months to recover. This definitely effected my work and I had to re-organise myself. As everyone I thought of getting some interns and employees but that did not work either. I spent my time, energy and money to make them upto speed but did not succeed either. It was difficult to part ways with some of them but I am happy that we did that in good terms. It was a good experience which I think can come only with few mistake. I learnt one very important lesson “Never hire a full-time until I am 100% satisfied”.

The formal registration of the company did not happen until May 2016. It is one marathon task as well. Working with Charted Account to get all documentation is not fun but it has to be done anyway. For registration I had to also give a company name. I spent good amount of time think about it. I was looking for some inspiration/help which I got from Ranga Shankara, a theatre in Bangalore and very near to my office. On my way to back from daily visit to a coffee shop I saw the board for theatre festival “Youth Yuga”. In hindi “Yuga” means “Era”, which made me think that is an era of cloud computing. So why not name my company “CloudYuga”. I took the “.guru” domain as in next year or two I would focusing on trainings.

Till Dec’15 to July’16 we worked from Bangalore Alpha Lab and then moved to our own office. It was fun to see the our own office taking shape.

_20161130_081246

Throughout the year I was engaged with Docker Community, which helped me both professionally and psychologically. I became part of Docker Captain’s program, which was a good confidence booster. In Bangalore I organised Docker meetups, which kept me well connected with local community. On my own I attended different international conferences DevConf’16, DockerCon’16 and LinuxCon/ContainerCon’16 & spoke in two of them .

When I started last year I told my family that lets see for 6 months and if things does not work out then I can go back to full time again. Its been year and I have things in pipeline for next 6 months, which is good. My family supported me very well, specially my wife Kanika who also joined to work with me part time since last few months.

Till now my focus has been training than consulting, which I believe would continue for some time. I see good amount skill gap in adopting container technologies.. good for me !!. Over the year I got some corporate clients for trainings which I think would continue to grow. Here is the group photo of the container (Docker) training I delivered today in Pune.

Some of learning from last year’s experience are:-

  • There are more good people in the world than we think. They are willing to help you.
  • Reach out to people with helping hand.
  • Give priority to health.
  • Be true to yourself and things would fall in place.

Its been a fun ride with lots of new experienced. Lets see how far we can go !!

Docker Mentor Week 2016 – Bangalore

Docker organised Global Mentor Week around the world between 14-19th Nov’16. In Bangalore we scheduled it on 19th Nov at Microsoft office. We divided the group into two groups Beginner and Intermediate of 125 each. Out of which ~60 turned up for each session.

The content for the mentor week was shared by the Docker, which had hands-on exercises for basic and intermediate level.  Microsoft provided Azure pass for every participant so that we all can have same working environment. But during the workshop we faced some internet issue, so everyone could not hands-on on that day.  But with Azure pass and labs, participants can try out the hands-on later.

For the beginner level we had four mentors Sreenivas MakamBathrinath Raveendran, Ratheesh T M  and myself. Sreenivas did the heavy lifting by walking through the Docker basics and labs. He also shared the notes to try out Docker Mentor Week’s lab on Azure. We had the beginner session between ~9:40 AM to 12:145 PM.

After the lunch we did the intermediate training. As the internet was not working, we decided to share the concept of Container Orchestration in general and then with Docker Swarm we showcased a sample application. I used the content from my LinuxCon/ContainerCon workshop which I did last month in Berlin.

After that Ajeet showed how to prepare Docker Swarm cluster on Azure and run & scale the sample application.

Both sessions were very interactive. I hope more people would have joined from the confirmed list. I had to say no to few group members as they could not get the confirmed ticket.

Thanks to Pracheta, Usha, Surubhi  and Sudhir form Microsoft for helping us with the Venue and Azure Passes.

LinuxCon ContainerCon 2016 – Berlin Germany

LinuxCon, ContainerCon 2016 in Berlin was very special for me, as this is the first time I represented my company CloudYuga as a speaker in an international conference. The event was scheduled between 4th to 7th Oct.’16 .

I reached there on 3rd Oct’16 and got a chance to meet Jim Zemlin Executive Director of  The Linux Foundation. On 4th, during the keynote Solomon Hykes, Founder and CTO of Docker open-sourced Infrakit, which is a toolkit for creating and managing declarative, self-healing infrastructure. It is currently used in Docker for AWS and other similar solution. Later in the day I attended sessions on Comparing Container Orchestration tools by fellow Docker Captain  Adrian Mouat, Cgroups session by Michael Kerrisk and Mircoservices vs Reverse-Proxy via Emile Vague. In the evening I attended the speaker and sponsor’s party at House of Weekend, Berlin.

On 5th I spent most of the time preparing for container orchestration workshop on 7th. Though I attended few sessions like Getting started with Mesos Marathon by Brenden Matthews,  OCI session by Qiang Huang, Docker Orchestration via Aaron Lehmann,  Phil Estes talk on container security and Migrating traditional & existing app on container by  Scott McCarty. In the evening I attended 25th Anniversary of Linux Celebration The Great Orangery at Charlottenburg Palace. There I got the chance to meet Dan Kohn, Executive Director of The Cloud Native Computing Foundation and discussed about the course I did for Linux Foundation, earlier this year.

On 6th attended after attending one or two sessions I joined fellow Docker Captains for Jerome Docker Swarm workshop. After the workshop Solomon joined us for Q &A. He shared an interesting perspective on Docker – Docker which has been there for quite some time and Docker which is now evolving …

After that we had Docker Captain’s party at some nearby restaurant.

On 7th I delivered the hands-on session on container orchestration, in which I covered Docker Swarm, Kubernetes and Mesos Marathon. For Docker Swarm and Marathon I gave instances on DigitalOcean to each participant. For Kubernetes I created a cluster on Google Cloud and had a namespace created for each participant. I heard some good feedback about the workshop after the session was over.

After the session I went to attend Docker Distributed Summit for rest of the day. The summit had very good technical content. All of the videos are recorded and would be shared soon. I could not attend the second day of Summit as I had come back on 8th.

As always this had been a great experience. Learned a lot, met many interesting people and made some new friends.

People have been asking me who is funding your foreign trips as I attended DevConf in Brno,CZ and DockerCon in Seattle earlier this year as well.  I have been funding my own trips, which I think as investments. I got few leads from this conference as well. Hope I am in right path by doing so. Let’s see if I would have another blog post for overseas conference or not.

Bangalore Docker Meetup #21 at Infosys

We had our last Docker Meetup at Infosys on 9th July’16. Though some 300 RSVPed but only 80 people attended. It is good to see company like Infosys coming forward and hosting such meetup. Thanks to Ganesh from Infosys for taking the lead here and making it happen.
Docker Meetup #21 @InfosysHe started the meetup with introduction about Infosys and then introduced the speakers. After that I talked about my DockerCon experience and briefed everyone about announcements made at DockerCon’16 like Docker 1.12, new Swarm mode, AWS and Azure beta, Window and Mac Beta etc.

Docker and DevOps Meetup

Mohit and I met at  first GitHub meetup of Bangalore in March’16 and discussed that it would be a good idea to do a joint meetup of Docker and DevOps groups of Bangalore. Later we followed up and decided to do it on 30th April’16. It was hosted at IBM’s EGL office in Bangalore. We decided to do a full day event as we received a good number of topic suggestions. 250 people RSVPed for the meetup and ~100 people came for the meetup.

Docker and DevOp meetup - Apr'16

I started the meetup by going through the Docker and the Three Ways of DevOps white paper to reiterate why Docker and DevOps goes hand in hand in recent times.

After that Jeeva S. from IBM talked about doing CI/CD using GitHub, Jenkins, and Docker. After talking about Jenkins 2.0 features, he showed how he built a CI/CD pipeline using Docker 3rd Birthday App and Jenkins. Another gentleman from IBM then talked about how IBM uses Jenkins to do CI for the Power Platform. Sudipto Biswas and Manjunath K  then shared their team’s experience of running 10K containers on one physical machine.

Next session was from Burr Sutter of Red Hat, who gave an excellent presentations on Mircoservices and DevOps. He compared Docker and Microservices to magic, which we think is going to solve all the world’s problems. Is it ?  Docker and Microservices are really hot these days but in some time this is going to stabilize and we’ll move to some-thing new.

Docker and Mircoservices hotness

But that does not mean companies should not adopt them. In the near future they would become normal and we don’t think of them as a universal solver of the world’s problems 🙂 . He also shared a blueprint of the journey which every company has to go through to adopt DevOps and Microservices.

After that Pradeep Chhetri gave a good introduction of Mesos and how we can use it for doing CI/CD using Jenkins framework.

Post lunch we had Abhishek Narain from Microsoft, who talked about Azure container service and how we can use Mesos or Docker Swarm as a container orchestration engine on the Azure Platform.

After that Harendra Singh and Chetan Tarale from Shippable gave a presentation on Shippable platform with a demo.

Last presentation of the day was from Balaji of Calm.io, who talked about doing CI/CD with Jenkins & Calm.io. He did not pitch about their platform and focused mostly on how to do CI/CD and the need of DevOps, which is a really good thing to do in such community events.

Next Bangalore Docker Meetup is scheduled on 4th June’16 and we’ll keep that Developer centric this time.

3rd Docker Birthday Celebration

Bangalore Docker Community celebrated Docker’s 3rd Birthday on 26th March’16 at Huawei’s Bangalore office. Suraj has written a  great report about the event. So I would cover some other points.

  • More than 400 RSVPed for the event, so we had to divide the group iWP_20160326_09_22_17_Pron two batches and we were expecting ~100 in each. Due to long weekend we had ~70 people in first batch and ~35 in second batch. We could have easily accommodated everyone is one batch, if people have updated RSVPs accordingly. Please do not RSVP is you don’t plan to come.
  • Few of us discussed that in India we mostly have the user base and hardly have any committer to Docker.  To start contributing back to the project,  we decided to start doing beta testing for Docker releases.
  • Also we thought of doing small hackathon’s in which we’ll start going through Docker code base and learn from it.

I hope participants have learned something new during the training. I would like to thank Venkata Nagesh, Sreenivas Makam, Janki Chhatbar, Shubham Minglani, Suraj Deshmukh, Durga Prasad, Zeeshan Ahmed  for volunteering as mentor.  Special thanks for our hosts at Huawei, Krishna and Vinay.
