Docker image for Pound.
This image is generic, thus you can obviously re-use it within your non- related EEA projects.
Using Docker-Compose is the quickest way to start a container and connect the
available webapps through the ‘links’ parameter. Here is a basic example of a
docker-compose.yml file using the
eeacms/pound docker image:
pound: image: eeacms/pound ports: - "80:80" env_file: - pound.env links: - webapp webapp: image: razvan3895/nodeserver
The application can be scaled to use more server instances, with
$ docker-compose scale webapp=4 pound=1
$ docker run --env BACKENDS="192.168.1.5:80 192.168.1.6:80" eeacms/pound:latest
The servers are written as
server_ip:server_listening_port, separated by
spaces (and enclosed in quotes, to avoid issues). The contents of the variable
are evaluated in a bash script that writes the Pound configuration file
It is mandatory that the configuration file is mounted at /etc/pound/config.cfg
$ docker run -v conf.d/pound.cfg:/etc/pound/config.cfg eeacms/pound:latest
This is the preferred way to start a container because the configuration file can be modified locally at any time. In order for the modifications to be applied, the configuration has to be reloaded, which can be done by running:
$ docker exec <name-of-your-container> reload
As Pound has close to no purpose by itself, this image should be used in
combination with others (for example with Docker
Compose) Pound can be configured by
modifying the following env variables, either when running the container or in
docker-compose.yml file, preferably by supplying an
.env file in the
