I'm new to CasaOS and fairly new to docker but have been able to
deploy some containers on my Zimaboard.

I have manually installed SWAG with the compose file which works fine
but was wondering is it possible to run some post shell scripts
automatically once the docker container is started.  I want to
installed keepalived as i plan to run two zimaboards with either an
active/active or active/passive swag reverse proxy.  The docker images
do not come with this package automatically deployed but it is
available via apk.

I have been reading on the internet and have tried using command: sh
script and entrypoint: sh script  in the compose file but they don't
seem to work and the swag services don't start or the container just
restarts.  Another method I have found is to use a dockerfile but i
don't see anyway of do this with casaos.

Can anyone help suggest a method i can run a post script automatically
each time the container is started.  This way when i come to update
the container the package will be reinstalled and hopefully start
keepalived with a config file I will put on an attached volume.

Any help would be appreciated.
