Init Script

If you have a script that needs to be executed repeatedly when running a container, you can use the Init script. The Init script runs from the root directory (/) of the container and is executed when the container starts.

It is commonly used to write scripts that execute your application.

Shell environment limitations

The Init Script is executed using /bin/sh, which has the following limitations:

• Only POSIX-compliant sh commands are supported.

• Bash-specific syntax (e.g., [[ ]], source, arrays, or bash shebangs) cannot be used.

• Existing scripts written for bash must be adapted to be compatible with /bin/sh.

Useful Resources:

• POSIX Shell Standard: Official documentation for the standard /bin/sh command language.

In the Container Settings page, under the Init Script section, you can write the execution commands. Once you're done writing, it will be saved automatically, and these commands will automatically run when the container starts.
