Dispenser

This tool manages Docker Compose instances by constantly looking for new versions of images to deploying seemlessly.

Dispenser works as a daemon that runs in the background of the host server.

Example config

This is an example config that you can base yours around. This config listens to changes on the nginx:latest image and reloads the docker compose found in the directory /opt/dispenser/example.

delay=60 # Will watch for updates every 60 seconds

[[instance]]
path = "example"
images = [
  { registry = "docker.io", name = "nginx", tag = "latest" }
]

Build

RPM (RHEL)

To build rpm make sure you have the following installed:

• cargo: Rust package manager and build tool
• rustc: Rust compiler
• make: Run make files
• rpmbuild: Tool to build RPMs

Once these dependencies are installed run:

make build-rpm

This should create a file called roughly ../dispenser-$VERSION.x86_64.rpm.

Deb (Debian & Ubuntu)

To build deb make sure you have the following installed:

• cargo: Rust package manager and build tool
• rustc: Rust compiler
• make: Run make files
• dpkg-dev: Tool to build DEB files

Once these dependencies are installed run:

make build-deb

This should create a file called roughly ./dispenser.deb.
