Shows version

Initializes specified root directory as a ctcli dir.

ctcli --root /path/to/dir init

Installs a package into specified root folder. Example:

ctcli install /path/to/package.tar.gz

First it creates tmp dir and extracts an archive. Then it creates oci image config and rootfs folder. Then it copies unpacked images to current-release folder. Makes symlinks for logs folder and configs. Creates a zero backup.

Upgrades a release with binaries contained in given package. Backups previous release. Example:

ctcli upgrade /path/to/package.tar.gz

Creates a tmp dir and extracts the archive. Then it creates oci image configs and rootfs folders. Next it checks diff between apps in package and apps in current release and prompts for upgrade. If user decided to upgrade, creates a backup, deletes apps from current release and copies files from tmp folder to current release.

Deletes a release completely. Example:

ctcli delete

Starts current installation. Example:

ctcli start [app]

Stops current installation. Example:

ctcli stop [app]

ctcli logs [--tail <n>] [-f] <app>

Options:

• --tail 100 - Show latest 100 bytes
• -f - Follow log file

Show current status. Example:

ctcli status

Execute a command inside a container. Example:

ctcli exec busybox cat /etc/hosts

Makes an archive containing current-release/, data/ and config/ folders and puts it into releases/ folder

• --ignore-data flag disables data/ folder backup
