Error while running docker container

I am running a docker image using the following command.

docker run -it -p 8080:8080 -p 29418:29418 --rm \  
-e AUTH_TYPE='DEVELOPMENT_BECOME_ANY_ACCOUNT' \
-v /home/gerrit-site:/home/gerrit/site \
-v /home/nidhi/.ssh/id_rsa.pub:/root/.ssh/id_admin_rsa.pub \
-v /home/nidhi/.ssh/id_rsa:/root/.ssh/id_admin_rsa \
-e GERRIT_ADMIN_USER='admin' \
-e GERRIT_ADMIN_EMAIL='[email protected]' \
-e GERRIT_ADMIN_FULLNAME='Administrator' \
-e GERRIT_ADMIN_PWD='mysecret' \          
-e GERRIT_ADMIN_PRIVATE_KEY='/home/gerrit/ssh-keys/id_admin_rsa' \
-e GERRIT_PUBLIC_KEYS_PATH='/home/gerrit/ssh-keys' \
-v /home/nidhi/.ssh:/home/gerrit/ssh-keys \
--name gerrit admin_gerrit

I know the command is right cause I had used this command before and it worked perfectly fine. But now, when I run this command I get the following error,

Error response from daemon: Cannot start container 2c9514c3b0d953344e66525d083c7ec3921cb9cde2185f43ec3bec2579597485: stat /home/nidhi/.ssh/id_rsa: permission denied

I checked the permission for the ssh public and private keys. The permission is 700 and is owned by nidhi. Please can someone point out what my error is.

When docker runs, the uid in your container will likely not match the uid on the host. So with a host volume containing files with 700 permissions, that will not be readable by the uid inside the container. Three options come to mind:

  1. To keep the 700 permissions and same image, you'd need to chown the file on the host to match the uid inside the container.
  2. You can use a named volume instead of a host volume, add your credentials to that named volume, and then set permissions inside there to match the containers where you'll use the volume.
  3. Or you can use a different image that's been rebuilt to change the uid to match your own on the host.
