Auto-Start Services in Container Instances¶

Each container instance in Compute Cloud includes an s6 supervisor daemon that automatically starts designated services at boot time.
To enable auto-start for your custom service, simply register it with s6.

Prerequisites¶

Logged in to your d.run account
A container instance has been created via Compute Cloud, and its status is Running

Register a Custom Service¶

Create a directory under /etc/s6/ with the name of your service, and inside it, create a Bash script named run.
Place the service startup command inside the run script.

Note

After registering a custom service, you must shut down and save the container image.
This ensures the configuration is persisted and the service will auto-start on the next boot.

Example 1: Auto-start Nginx¶

mkdir /etc/s6/nginx  # Register a custom service
cat <<EOF > /etc/s6/nginx/run  # Create the service start script
#!/bin/bash

echo "Starting Nginx..."

exec nginx  # Start nginx
EOF

Example 2: Auto-start a Python HTTP Script¶

mkdir /etc/s6/python_http  # Register a custom service
cat <<EOF > /etc/s6/python_http/run  # Create the service start script
#!/bin/bash

echo "Starting python http..."

exec python /root/data/http.py
EOF
