Docker-compose overview | features | production installation | uninstallation

docker-compose:

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

Features of docker-compose:
  • Multiple isolated environments on a single host
  • Preserve volume data when containers are created
  • Only recreate containers that have changed
  • Variables and moving a composition between environments
Common use cases:
  • Development environments
  • Automated testing environments
  • Single host deployments
Install docker-compose:
# curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Check docker-compose installation:
# docker-compose version
docker-compose version 1.24.0, build 0aa59064
docker-py version: 3.7.2
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.1.0j  20 Nov 2018
