nginx-hosts-reload is a Go project that monitors changes in the /etc/hosts file and reloads the nginx process when changes are detected.

• Monitors the /etc/hosts file for changes
• Sends a SIGHUP signal to the nginx process when changes are detected
• Provides a simple API to start and stop the monitoring process

To run Nginx Hosts Reload, you must compile the code and run the binary file.

go build
./nginx-hosts-reload

By default, the utility will run in the background and check the modification time of the /etc/hosts file every 5 seconds. The nginx process name and the "master process" cmd substring will be used to find the nginx process ID.

• -log-level: Specify the log level (default: info)
• -interval: Specify the interval for checking the hosts file for changes (default: 5s)
• -process-name: Specify the process name to check (default: nginx)
• -cmd-substring: Specify the cmd substring to check (default: master process)

The Makefile has several options:

• build: Builds the Go project and creates a binary in the bin directory.
• build_amd64: Builds the Go project for the Linux, AMD64 architecture and creates a binary in the bin directory.
• test: Runs vet, unit, and integration targets.
• vet: Runs Go's vet tool to check for suspicious constructs in the source code.
• unit: Runs unit tests on the project.
• integration: Builds a Docker image and runs integration tests.
• image: Builds a Docker image using the Dockerfile in ci/docker directory.
• docker_start: Starts a Docker container with the previously built Docker image and copies the binary to the container.
• docker_stop: Stops and removes the Docker container.
• docker_exec: Runs a bash shell inside the Docker container.
• bosh_release: Creates a BOSH release tarball from the project source code.
• gh_actions: Runs the act tool to emulate github actions locally.
• clean: Deletes the bin directory, the bosh-release-tarballs directory, and some other generated files.
