Execute command on docker container from remote machine

Question

I have docker running on Host. There are two docker containers on this host i.e container_1 and container_2. Now I want to execute some commands on container_1 from my remote dev machine.

pipe separated commands i.e,

sudo docker exec -it  container_1 sudo find <dir> - type f -iname *_abc_* -print0 | du --files0-from - -b | awk 'BEGIN{sum=0} {sum+=$1} END{print sum}'

Form above command only first command till first pipe execute on docker container and next set of command execute on host.

I am using python fabric api to execute this from remote machine.

Is there any way to execute this full command on container from remote machine ?

that's because pipe command actually gets executed on your host, try this, it may work for you: sudo docker exec -it container_1 bash -c "sudo find - type f -iname _abc_ -print0 | du --files0-from - -b | awk 'BEGIN{sum=0} {sum+=$1} END{print sum}'" — Boynux
