Run a Stable LizardFS
After some evaluation, LizardFS is my recommended distributed file system. It provides redundancy for huge amounts of storage and is fast enough to serve as docker storage backend. But still there are a lot of pitfalls that could make you loose your data. Here is a collection of my learnings.
Docker Swarm and GlusterFS
Docker swarm is very easy to setup and maintain. It distributed containers over several nodes in a cloud, offers load balancing, redundancy, failover, smooth updates. But local volumes stay locally, so you need a cluster or network file system. That's where gluster enters the stage.
Setup OpenLDAP Server in Docker
Setup an OpenLDAP server in a docker container, including a LDAP Administration Manager web interface, requires just four commands in a Linux bash. Three more to enable TLS.
