How to get the docker containers information with Ruby and monitor it -

-

i want containers' stats. eg: cpu, memory

i know command docker stats <container name>, when type command, blocking in foreground(like typed top command)

but want information ruby.

then decide action information, such restart container or else.

thanks ~

you should access docker remote api not docker cli

so if want container stats, can through get /containers/(id)/stats api , parse response ruby.

also, found ruby repo might helpful.
