Docker 🐳

It has been a while since I have posted, since Docker Bootcamp was published I have been hard at work on the second edition of Mastering Docker for Packt↗ which is now available from https://www.packtpub.com/en-us/product/mastering-docker-9781789618686↗ as well as Amazon and all other book stores.

I haven’t posted here in a while as I have been busy writting my third book. I am pleased to say that Docker Bootcamp will be published in the next few weeks by Packt↗ . It is available for pre-order now↗ .

I had some time today, so I thought I would combine two posts I have been planning on writing for a week or two, looking at Docker 1.13 and also Minio. It is important to note before you read further that this post does not cover using Mino as a storage backend for containers. It is about launching a distributed Minio installation in a Docker Swarm cluster and consuming the storage using the Minio command line client and web interface. ...

Following on from the post I wrote on Portainer; Portainer, a UI for Docker↗ There was a lot of great feedback, like the following from Aleksandr Blekh, Ph.D.↗ ; Great post, thank you! Could you briefly clarify why/when one would want to prefer Portainer to Rancher and vice versa. It would be great, if you could also touch on benefits of using Docker UIs versus Kubernetes-based PaaS, specifically OpenShift (which has UI for Docker container management). ...

I thought it was about time, as I had some to spare today, to have a play with one of the new feature of the Elastic family of products I have yet to try. Beats is the platform for single-purpose data shippers. They install as lightweight agents and send data from hundreds or thousands of machines to Logstash or Elasticsearch. I have used an ELK stack before↗ but never for metrics, it always been for more traditional log files and tools such as Zabbix↗ have been my goto for metrics. ...

I have more and more people at work asking me about Docker and Kubernetes↗ , so I thought it would be good to write down some instructions on bringing up a small test lab on my laptop. I had initially assumed that I would have to spend some time configuring a Vagrant box for this, but then I spotted the Minikube project↗ . Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day. ...

Part of my daily routine is to go through Reddit, RSS feeds and also wading through the MediaGlasses twitter↗ account where I follow loads of technical people & companies. Over the lat week or so I have seen Portainer mentioned quite a lot, particularly since it has now had over 1M + pulls on the Docker Hub; Looks like Santa left @portainerio a nice christmas gift.. 1 Million @docker Pulls!!! Thank you all for helping us achieve this milestone. pic.twitter.com/tey47Hhkwo ...

At the start of this month Docker purchased a storage startup called Infinit↗ . We’re joining @docker! 🐳 🎉 https://t.co/iCTBd0bWLw — Infinit (@infinit) December 6, 2016 Up until then I had only heard of their commercial offering which can be found at https://infinit.io/↗ which on the face of it has nothing to do with container storage and is a Dropbox equivalent. Concepts Before we roll our sleeves up and install, configure & user Infinit we need to cover a few of the terms. ...
