Trying to run the command below:

docker container exec container-name echo '. $HOME/.asdf/asdf.sh' >> /root/.bashrc

but I'm getting the error below:

warning: An error occurred while redirecting file '/root/.bashrc'
open: Permission denied

I just created the container. I can get into the container as root and execute the same command without error. Does anybody know what I'm missing?

CodePudding user response：

You are trying to write in your host's root user .bashrc. It is good that you didn't run this as user root on host.

I think this is what you actually want:

docker container exec container-name sh -c 'echo . $HOME/.asdf/asdf.sh >> /root/.bashrc'

Also you can use /root instead of $HOME since you already use that in the second part of the command.
