Environment variables can be set by adding the --env argument in the command line, for example:

--env KEEPALIVED_PRIORITY="100" --detach osixia/keepalived:0.2.2

#### Link environment file

For example if your environment file is in : /data/environment/my-env.yaml

docker run --volume /data/environment/my-env.yaml:/container/environment/01-custom/env.yaml \
--detach osixia/keepalived:0.2.2
--detach osixia/keepalived:0.2.3

Take care to link your environment file to `/container/environment/XX-somedir` (with XX < 99 so they will be processed before default environment files) and not directly to `/container/environment` because this directory contains predefined baseimage environment files to fix container environment (INITRD, LANG, LANGUAGE and LC_CTYPE).
