Recipes for docker

[enboig]

I am backing up a docker app having a mariadb container. If container is up I want to use your recipe; but if it is down, I would like to backup the mariadb data folder. Is this possible?

run docker exec mariadb sh -c '/usr/bin/mariadb-dump -u dumps database'
if it fails:
include ./mariadb_data_folder/
endif

Solved, I can
before: "(dump || touch database/.nobackup )"
finally: "rm -f database/.nobackup"

Not tested, but it should work.

In case anybody is interested:

sources:
  - label: joplin-files
    path: /root/docker/joplin
    hooks:
      before: "docker container inspect -f '{{.State.Running}}' joplin-db >/dev/null 2>&1 && touch data/postgres/.nobackup || true"
      finally: "rm -f data/postgres/.nobackup"
  - label: joplin-database
    command_dumps:
      - name: joplin.psql
        command: "docker container inspect -f '{{.State.Running}}' joplin-db >/dev/null 2>&1 && docker exec joplin-db sh -c 'pg_dumpall -U joplin' || echo '-- container not running'"
