Docker Container access

[monicamillad]

Hello,
I was trying to access the container after running it but I didn't succeed

the command I used to run was

docker run -d --rm --ip 10.20.30.10 --volume /etcd-vol --volume /etcd_backup --name etcd gcr.io/etcd-development/etcd:v3.4.27 /usr/local/bin/etcd --data-dir=/etcd-data/etcd-data --name etcd-node-0 --initial-advertise-peer-urls http://10.20.30.10:2380 --listen-peer-urls http://0.0.0.0:2380 --advertise-client-urls http://10.20.30.10:2379 --listen-client-urls http://0.0.0.0:2379

and it ran successfully, but after that I was trying something like docker exec -it etcd bash or docker exec -it etcd sh but I always get this error OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "bash": executable file not found in $PATH: unknown

so I was wondering if I doing something wrong or I missed something ,, or maybe the container doesn't have bash or sh I don't know

Hey @monicamillad - Thanks for your question.

To minimise attack surface the standard etcd images are based on distroless and do not contain a shell, refer:

etcd/Dockerfile

Line 2 in 245b58a

FROM --platform=linux/${ARCH} gcr.io/distroless/static-debian12

If you need to interact with etcd you can docker exec to run the etcdctl utility available inside the container. For example:

# Check etcd endpoint status
docker exec <name> etcdctl endpoint status -w table
