Docs for docker-utils.go

Usage

The docker-utils.go file in the utils package provides a function to check if the current environment is running inside a Docker container. This can be particularly useful for applications that need to adjust their behavior based on whether they are running in a containerized environment.

IsRunningInDocker

Description

IsRunningInDocker checks various indicators to determine if the current process is running inside a Docker container.

Usage

runningInDocker := IsRunningInDocker()

Reference

This function does not take any parameters and returns a boolean value:

Return Value Type Description
runningInDocker bool Returns true if the current process is detected to be running inside a Docker container, otherwise false.

Detection Mechanism

  1. Checks for Docker-specific environment variables like REMOTE_CONTAINERS_IPC, REMOTE_CONTAINERS_SOCKETS, REMOTE_CONTAINERS_DISPLAY_SOCK, and REMOTE_CONTAINERS.
  2. Looks for the presence of the /.dockerenv file.
  3. Reads the /proc/1/cgroup file to check for the docker keyword, indicating that the process is running inside a Docker cgroup.

This utility function is essential for applications that need to dynamically identify their running environment, especially when differentiating between containerized and non-containerized contexts.
