When we use crontab or the deprecated /etc/rc.local file, we need a delay (e.g. sleep 10, depending on the machine) to make sure that system services are available. Usually, systemd (or upstart) is used to manage which services start when the system boots. You can try use the similar configuration for this:
# /etc/systemd/system/docker-compose-app.service
[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service
[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
[Install]
WantedBy=multi-user.target
Or, if you want run without the -d flag:
# /etc/systemd/system/docker-compose-app.service
[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service
[Service]
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitIntervalSec=60
StartLimitBurst=3
[Install]
WantedBy=multi-user.target
Change the WorkingDirectory parameter with your dockerized project path. And enable the service to start automatically:
systemctl enable docker-compose-app
