Docker Compose Notes

Docker-compose is a client for arranging docker resources.

Here are some notes:

depends_on

• This param define the compose run sequence, Not the build sequence

• run sequence do not mean the ready sequence. Some image need 10+ or more seconds to be ready (like mysql, many engines need to run)

  Generally speaking, it’s almost useless

networks

• network’s aliases make alternativle hostnames which can be used in other containers that under same network
• pid works like aliases, every service may define only one pid, so it’s not as good as aliases
• network can use driver, it’s bind the basic networks which include host, bridge, none
• networks driver’s behavior are different on different system, as docker runs under virtualbox on MAC or WIN
• if the network want to bind and publish ports to the host network on MAC or WIN, you should use bridge. But use host on LINUX
