FAQ — Frequently Asked Questions

What is the difference between Networks and the other groups?

Each group in this Docker CLI cheat sheet covers a distinct area. Networks focuses on its specific scope, while the other groups and the remaining groups cover networking, storage, security and diagnostics respectively.

How do I check the installed Docker CLI version?

Run the version command (usually docker version or docker --version). The output shows the client and, when applicable, the server version.

Why does Docker CLI return ‘permission denied’?

A ‘permission denied’ error in Docker CLI usually means the current user lacks sufficient privileges or credentials are not configured. Check: (1) assigned IAM/RBAC roles, (2) an active authentication context via the corresponding login command.

How do I filter Docker CLI output by status or name?

Use flags such as --filter, --selector or --query depending on the tool. You can also pipe into grep or jq to process JSON: 

docker list | grep RUNNING

What is the fastest way to debug a Docker CLI error?

Add the verbose flag (--verbose, -v or --debug) to the failing command. This reveals the underlying HTTP/API calls and the full error response body.
