Backup Named Volume

How I backup named volumes.

• Using a ubuntu image, we mount the named volume (myproj_dbdata) to a /dbdata folder inside the ubuntu container.
• Create a new folder inside the ubuntu container named /backup.
• Create an archive containing the contents of the /dbdata folder and we store it inside the /backup folder (inside the container).
• Mount the /backup folder from the container to the docker host (your local machine) in a folder named /backups inside the current directory.

docker run --rm -v myproj_dbdata:/dbdata -v $(pwd)/backups:/backup ubuntu tar cvf /backup/db_data_"$(date '+%y-%m-%d')".tar /dbdata

NPM

From the same directory where your gulpfile is located, install all the node modules for the project first:

$ docker run --rm --name node -v `pwd`:`pwd` -w `pwd` node npm install

Gulp

From the same directory, you can also use docker to run gulp. For example:

$ docker run --rm --name node -v `pwd`:`pwd` -w `pwd` node ./node_modules/.bin/gulp sass
