imx-docker: bash command not found

[AlanWen]

Hi, I am trying to build the imx bsp from docker container. I follow the github nxp-imx/imx-docker repo to build the docker image & its container.

nxp-imx/imx-docker: i.MX Docker (github.com)

After running up the container and it caused some failures in bitbake, so I tried to attach the container to fix it. But the container can't run any bash command when I attach to it as shown below.

user@0882fd94a700:~/Downloads/nxp/imx_docker$ ls
bash: ls: command not found
user@0882fd94a700:~/Downloads/nxp/imx_docker$ bitbake
bash: bitbake: command not found

If I build the base image as ubuntu:20.04 and run a container like

docker run -it --name ubuntu2004 ubuntu:20.04 /bin/bash

 and it can use bash command.

Sample of the Dockerfile-Ubuntu20.04

FROM ubuntu:20.04

# Update system and add the packages required for Yocto builds.
# Use DEBIAN_FRONTEND=noninteractive, to avoid image build hang waiting
# for a default confirmation [Y/n] at some configurations.

    useradd -g $host_gid -m -s /bin/bash -u $host_uid $USER

# Yocto builds should run as a normal user.
USER $USER

ARG DOCKER_WORKDIR
WORKDIR ${DOCKER_WORKDIR}

I don't know what made the docker container can not use the bash command in the Dockerfile. Can some one help me figure this out ?

[AlanWen]

But with the script docker-run.sh and attached the container, the bash command failed. Now I figure the problem may be the docker volume arguments and bash command that something had conflict in docker-run.sh

docker run -it --rm \
    --volume ${HOME}:${HOME} \
    --volume ${DOCKER_WORKDIR}:${DOCKER_WORKDIR} \
    --volume $(pwd)/${IMX_RELEASE}:${DOCKER_WORKDIR}/${IMX_RELEASE} \
    "${DOCKER_IMAGE_TAG}" \
    $1

 If I replaced the $1 to /bin/bash and it would cause the command not found problem.

-->This is correct step, you can only use bash command after you run it.
