Setting up Docker with user namespaces on CentOS 7.4

The procedure below has been tested on a Digital Ocean VM with CentOS 7.4

# Install docker from RHEL’s standard repos
yum install -y docker

#
# We’ll activate the ‘user namespaces’ feature that defends against

Running docker-compose as a systemd service

Files

File	Purpose
`/etc/compose/docker-compose.yml`	Compose file describing what to deploy
`/etc/systemd/system/docker-compose-reload.service`	Executing unit to trigger reload on `docker-compose.service`
`/etc/systemd/system/docker-compose-reload.timer`	Timer unit to plan the reloads
`/etc/systemd/system/docker-compose.service`	Service unit to start and manage docker compose

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

[Unit]
Description=%i service with docker compose
PartOf=docker.service
After=docker.service
