Rocked

A simple utility to handle container

A tool built while I learn about containers and how they work.

This is based on the rubber-docker project.

Usage

You can run the command by either compiling it first:

# go build .

And then run it as:

# ./rocked
A simple utility to handle container.

Usage:
  rocked [command]

Available Commands:
  help        Help about any command
  run         Runs a process

Flags:
  -h, --help      help for rocked
  -v, --verbose   Enable verbose logging

Use "rocked [command] --help" for more information about a command.

The run command takes:

# ./rocked run -h
Runs a process

Usage:
  rocked run [flags]

Flags:
  -e, --env stringArray   Sets environment variables. It can be repeated
  -h, --help              help for run
  -i, --image string      Use the container image (default "Fedora")

Global Flags:
  -v, --verbose   Enable verbose logging

To pass a command to run, use the double - to mark the end of the command options:

# sudo ./rocked run -i Fedora -- /usr/bin/whoami

The -i flag is mandatory. For now, the path where the images should be placed is /tmp/test-chroot. The program will be then use the path plus the image name, for example, /tmp/test-chroot/Fedora.

For now, you can use the script in utils named prep_chroot.sh to download a Fedora or an Ubuntu container image in the current directory. Once downloaded, extract the archive to /tmp/test-chroot/{fedora, ubuntu}.

Levels

Here are some notes on the various levels.
