To build the container manually run these commands consecutively in the root directory:
This command builds the systemd component of the container. Systemd is included in both the centos:7 and centos:latest base containers, but it is not active by default. This Dockerfile deletes a number of unit files which might cause issues. From here, you are ready to build your base image.
docker build --rm -t local/c7-systemd . -f Dockerfile.systemd
This command builds the ICTfax server on top of the systemd container
docker build --rm -t local/c7-systemd-httpd . -f Dockerfile.app
In order to run a container with systemd, you will need to mount the cgroups volumes from the host. To run the container execute this command:
docker run -ti --tmpfs /tmp --tmpfs /run -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 80:80 local/c7-systemd-ictfax
This container is running with systemd in a limited context, with the cgroups filesystem mounted. There have been reports that if you're using an Ubuntu host, you will need to add -v /tmp/$(mktemp -d):/run in addition to the cgroups mount.
For this to work on windows WSL must be activated so that systemd is exposed
