These images don't contain Bash. They're based on Alpine Linux, but can you use docker exec -it with-contenv sh. This will give you a command line in the container with environment variables loaded.

I hope that helps. Please let me know so I can close out this issue if this has resolved your issue.

Yes. You can close it. I use ash for now from alpine linux.
I have few questions regarding the redis-server and redis-cli,
I want one Generic Redis Server Container and then 'N' number of Redis-CLI Container(with only the redis-cli tools)
I wanted only the redis-cli container to get created when i run the below docker-compose file
docker-compose.yml file
Original compose-file
rcli:
image: redis:latest
links:
- redis
command: redis-cli -h redis

Converting to alpine linux:
rcli
image: smebberson/alpine-redis
links:

• redis
  command: redis-cli -h redis

Using Docker Network options with the link below can we achieve what am intended?

I wanted to call the below compose command from the webapp, the idea is to share the redis-server container with mulitple users only via redis-cli container exposing the redis-cli in web

docker-compose run rcli

[smebberson]

Let me look into this and get back to you.

[mkscala]

any luck? regarding the cli and server redis container with cli container exposed to web and allowing the cli and redis server talking to internal private n/w

you can install bash by adding to your Dockerfile:
RUN apk add --update bash && rm -rf /var/cache/apk/*

If you don't want to add to the size by installing bash, you can just run /bin/sh

Usually, an Alpine Linux image doesn't contain bash, Instead you can use /bin/ash, /bin/sh, ash or only sh.

docker run -it --rm alpine /bin/ash

docker run -it --rm alpine /bin/sh

docker run -it --rm alpine ash

docker run -it --rm alpine sh

--rm Automatically remove the container when it exits.

I hope this information helps you.

docker run -it --rm alpine /bin/ash

docker run -it --rm alpine ash

docker run -it --rm alpine sh

I hope this information helps you.

apk --update bash
if you need bash for other things also, like running scripts, this command could be useful.

Just replace BASH to SH
docker exec -it some-docker_app_1 sh

[NanheKumar]

docker exec -it CONTAINER_ID sh

@jansanchez is there any difference in any of these shells?
