Users can run JS7 containers from for specific user accounts:

Depending on the container management system

• containers are started from the root account.
  • Containers are not necessarily operated for the root account, but can be configured to switch to an individual account during start-up.
• containers are started from a non-root account.
  • Containers are operated for the same non-root account.

Ownership of directories and files in JS7 containers is managed

• by default from the respective Dockerfile that creates the image.
• at run-time by the respective entrypoint.sh script:
  • The script can switch user account if started from the root account.
  • The script will use the indicated account if started from a non-root account.
• individually if users create their own Dockerfile, entrypoint.sh script and image, see JS7 - Build Container Images.

Consider changes to the start-up of JS7 containers:

...

• If containers are operated for the root account then directories and files in exposed volumes are accessible to the root account only.
• If containers are operated for a specific account then directories and files in exposed volumes are accessible to the given account.

...

• Users are free to specify any user account for which the container will be operated.
• On start-up the container will actively own relevant directories and files to the user account specified.
• If a non-root Group ID is specified then group permissions will be handed over mapped to this group.

Using Run-time Accounts for Docker

Find examples for user account settings using the Docker run command:

...

# specify the root account's User ID and Group ID
docker run --user="0:0"

Using Run-time Accounts for Kubernetes

Find example for user account settings with Kubernetes® deployment files:

...

• Users are free to specify any user account for which the container will be started and operated. Alternatively, This includes to specify temporary user accounts can be specified.
• The user account specified has to be assigned the root group.
• For OpenShift® policies see Adapting Docker and Kubernetes containers to run on Red Hat OpenShift Container Platform
