Creates backup of services, secrets, configs, networks into json file with possibility to restore into different docker swarm cluster.
By default uses DOCKER_HOST and other envs (just like docker/cli)
Usage:
swarm-backup backup b.json
swarm-backup restore b.json
Internal networks, such as:
- bridge
- docker_gwbridge
- ingress
are not backing up.
Should be run on active manager.
Backup process creates new service evacuation to get secrets data on the current swarm manager.
