In a precedent 30.000-foot view series, we saw how AppArmor is used with Docker so container can be confined by default in an AppArmor profile.
With Docker 1.13, it’s now possible to deploy a stack from a docker-compose file. Let’s test that and deploy the Voting App on a 3 nodes swarm.
A couple of days ago, I sent a tweet regarding metrics exposition of the Docker daemon. As it got retweeted several times, I though this deserved additional details on how those metrics can be activated and how they can be sent to Prometheus, a great monitoring tool.
In this article we will see how we can deploy a 3 nodes MongoDB replica set (1 primary and 2 secondaries) in a Docker swarm cluster created with swarm mode.
Swarm mode: quick introduction
I’ve always be intrigued by the underlying of the Raft algorithm in Docker Swarm. This article aim to provide information to better understand what is happening behind the hood.
If you are using Docker on MacOS or Windows 10 Pro, chances are that you use the dedicated…
Since a couple of weeks, I really enjoy playing with Docker on ARM devices and especially testing swarm mode on little clusters. Below is an example of local cluster using swarm mode and made up of 2 PI2 and 1 PI3 (PI zero and CHIP should be…
When setting up a swarm cluster, by default I use Ubuntu machines (16.04 TLS). As we hear a lot about CoreOS, I wondered how a swarm can be deployed on a cluster of CoreOS hosts. Is there any reason to go CoreOS instead of Ubuntu (or other Linux distros) for “standard load” web applications ?
In a previous article, I quickly described the base of a CICD pipeline we deployed at TRAXxs (GitHub, CircleCI, Docker Hub, Docker Cloud, DigitalOcean were part of the technological stack used).
