Helper commands for docker because typing long docker commands is boring...
cd ~
mkdir bin
cd bin
git clone git@github.com:timlinux/docker-helpers.git
Now add this somewhere to your ~/.bashrc:
export PATH=$PATH:$HOME/bin/docker-helpers
Warning: Some of these commands may be destructive - use at your own risk and test on a test system before using in a production environment.
- backup_docker_databases.sh - backup all 'postgis' image based databases
- dcall - Commit all named containers. Provide a prefix for the image name.
The committed image will be in the form
<namespace>/<container name>. - dcalldated - Like the above command but adds a date stamp as the tag.
The committed image will be in the form
<namespace>/<container name>:01-Septmber-2014. - deall - Export all named containers. Exported containers will be named
in the form
docker-export-<container name>.tar. - dealldated - Export all named containers. Exported containers will be named
in the form
docker-export:<namespace>:<container name>:<date>.tar. - dimpall - Importing all exported containers from ~/exported-docker-containers
into
name:latest. - dipall - List the name and IP address of all named containers. Output
will be in the form
<container name> : IP Address. - dli - List all images. Shorthand for
docker images. - dnames - List all the names of named containers.
- dpasswords - Print the names and passwords from all named containers.
When you set up your container, print any passwords to stdout so they show up
in the docker logs command. Be sure to print the word
passwordin your stdout message as this is a simple grep operation. - dps - List all running containers. Short hand for docker ps.
- dpsa - List all running containers. Short hand for docker ps -a.
- drmc - Remove all stopped containers.
- drmi - Remove all images that have no tags.
- dstart - Start all exited containers. Typically you want to do this after a host reboot.
Note: Docker namespaces must be at least 3 characters long and less that 30
