Networking
To create a custom docker network on a host and avoid using --link:
docker network create --driver bridge testnet01
Defense of Baseimage
- Under certain circumstances when launching a container with -it the main application will not run. You must then execute the command manually. This does not happen with baseimage because of my_init.
- Many containers are missing basic diagnostic functionality like procps which provides the 'ps' command. This is instrumental in diagnosing whether an application is running correctly since docker does not rely on startup scripts.
