Putting your containers to sleep

Monitors network traffic to containers. If there is traffic, the container runs, otherwise the container is stopped/paused. for more details check out the Configuration section.

1. Clone the project

   git clone https://github.com/vmorganp/Lazytainer
   cd Lazytainer
   

2. Start the stack

   # if "docker compose" doesn't work, try "docker-compose"
   docker compose up

   This will create 2 containers that you can reach through a third "lazytainer" container
3. View the running container by navigating to its web ui at http://localhost:81. You should see some information about the container
4. Close the tab and wait until the logs say "stopped container"
5. Navigate again to http://localhost:81, it should be a dead page
6. Navigate to http://localhost:81 several times, enough to generate some network traffic, and it should start
7. To clean up, run

   docker-compose down

Lazytainer does not "automatically" start and stop all of your containers. You must apply a label to them and proxy their traffic through the Lazytainer container.

For examples of lazytainer in action, check out the Examples

Lazytainer starts and stops other containers in "groups" of one or more other containers. To assign a container to a lazytainer group, a label must be added. The label will look like this.

yourContainerThatWillSleep:
  # ... configuration omitted for brevity
  labels:
    - "lazytainer.group=<yourGroupName>"

To configure a group, add labels to the lazytainer container like this. Note that each is required to have a port(s) specified. These ports must also be forwarded on the lazytainer container

lazytainer:
  # ... configuration omitted for brevity
  ports:
    - 81:81 # used by group1 and group2
    - 82:82 # used by group2
  labels:
    # Configuration items are formatted like this
    - "lazytainer.group.<yourGroupName>.<property>=value"
    # configuration for group 1
    - "lazytainer.group.group1.ports=81"
    # configuration for group 2
    - "lazytainer.group.group2.ports=81,82"

Group properties that can be changed include:

If you would like more verbose logging, you can apply the environment variable VERBOSE=true to lazytainer like so

lazytainer:
  # ... configuration omitted for brevity
  environment:
    - VERBOSE=true

If using lazytainer, you MUST provide the following volume to lazytainer

lazytainer:
  # ... configuration omitted for brevity
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock:ro
