I am trying to run

$ apk add pkg

in an alpine linux based container that isn't starting up.

Can anyone tell what is wrong with the following commands.

$ docker run  --rm  --entrypoint myimage:mytag 'apk add wget curl vim lynx'
docker: invalid reference format.
See 'docker run --help'.

$ docker run  --rm myimage:mytag --entrypoint 'apk add wget curl vim lynx'
container_linux.go:262: starting container process caused "exec: \"--entrypoint\": executable file not found in $PATH"
docker: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "exec: \"--entrypoint\": executable file not found in $PATH".

$  docker run  --rm myimage:mytag --entrypoint '/sbin/apk add wget curl vim lynx'
container_linux.go:262: starting container process caused "exec: \"--entrypoint\": executable file not found in $PATH"
docker: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "exec: \"--entrypoint\": executable file not found in $PATH".

$  docker run  --rm  --entrypoint "apk" myimage:mytag 'add wget curl vim lynx'
apk-tools 2.7.5, compiled for x86_64.

usage: apk COMMAND [-h|--help] [-p|--root DIR]
           [-X|--repository REPO] [-q|--quiet]

回答1:

Your last attempt was almost correct syntax. You just need to remove the quotes around the arguments.

docker run  --rm  --entrypoint apk myimage:mytag add wget curl vim lynx
