Last week I deployed a jenkins container and a buildah container on docker in order to create docker images without requiring access to a Docker daemon.

Jenkins is considered by most people the best automation server around, it can automate almost any task using its plugins: can connect to any ssh capable hosts and run commands, execute ansible playbooks, run maven command, push packages or images to a remote repository, etc.

After completing Mumshad Mannambeth’s Certified Kubernetes Administrator (CKA) with Practice Tests course it was time to deploy my first kubernetes cluster for practice.

After having the graylog stack working it was time to add some security, even elasticsearch was running on an isolated network, some elements were exposed to the local network such as haproxy or rsyslog, that meant some flaw in their code could compromise the whole deployment.

I’ve been playing with the swarm deployment from my previous post too much, I’m completely sure because I was temporally banned from downloading images from hub.

Righting the wrong I though my last try was a failure, but I was wrong.

Last weekend I built a docker swarm using an ansible role and deployed elasticsearch, mongodb and graylog into it, it worked but was useless because no way of ingesting data was defined.

After last week’s break, and having managed to get the RHCE certification, it’s time I get on containers.

I did it, I’ve passed the EX294 exam and got my RHCE certification.

Overwhelming doubts I’ll take the Red Hat’s EX294 on three days, and I’ve to recognize I’m a bit anxious about it, may be, “a bit” is not the correct expression, I’ve a full cargo train of anxiousness.
