Docker Swarm

# list node
docker node list

# list all container all status
docker service ps --no-trunc <service>

# list container running in one of nodes
docker service ps -f "node=manager1" redis

# list container running only
docker service ps -f "desired-state=running" redis

# Swarm mode with task status 'rejected', is there a way find out why a task was rejected by agent
docker inspect <task id>

# change replicas
docker service scale <nama service>=50

# pindahan server
# ketika vm di-clone ke vm baru, ip dan hostname baru tapi ketika ketik:
docker swarm join-token manager
# hasilnya masih ip vm lama, solusinya:
sudo systemctl stop docker
sudo rm -rf /var/lib/docker/swarm
sudo systemctl start docker
# kemudian mulai bikin swarm baru:
docker swarm init
# kemudian coba cek lagi token manager, hasilnya sudah IP baru.
# hati hati semua service hilang :0
