You are strongly inspired to make use of VOLUME for any mutable and/or consumer-serviceable components of your picture. This script makes use of the exec Bash commandso that the final working software becomes the container’s PID 1.

They may then be capable of be searched for with frequent programming instruments, such because the Unix grep utility and even syntax-highlighted within textual content editors. These are typically referred to as “codetags” or “tokens”. Line feedback typically use an arbitrary delimiter or sequence of tokens to point the beginning of a comment, and a newline character to point the tip of a comment.
