Deploy CAE using Docker

Precondition: a Linux machine having docker installed

Docker

Pull Docker image from our docker registry

CODE

docker login --username MyCredentials --password MyPassword https://docker-registry.davidsystems.com:443
docker pull docker-registry.davidsystems.com:443/cae:latest

As an alternative you could also import a docker image from a file we provide.

CODE

docker import cae.tar.gzip

Remove previously running container (optionally)

CODE

docker stop cae
docker rm cae

Run container with CAE

CODE

docker run -d --name cae -p 8888:80 docker-registry.davidsystems.com:443/cae:latest

The CAE container is exposed on port 8888 for HTTP.

To handle HTTPS we recommend to run it behind a reverse-proxy that is doing SSL-offloading.

Adapt Settings Manually

Currently there are two options to adapt the settings files in the container

Edit the settings directly in the container

CODE

docker exec -it cae /bin/sh
apk add nano
nano /user/share/nginx/html/assets/settings.json

Overwrite the settings files using the docker cp command
CODE
```
docker cp ./mySettings.json cae:/usr/share/nginx/html/assets/settings.json
```
See Adapt Settings

Automatically Copying Settings Files From Host At Container Startup

(1) Create a docker volume

CODE

docker volume create caeVol

This creates a docker volume named caeVol which is mapped to folder /var/lib/docker/volumes/caeVol/_data.

(2) Copy your setting files to the volume on the host

settings.json

(3) Mount the volume when starting a container instance

CODE

docker run -d --name cae -p:8888:80 -v caeVol:/data docker-registry.davidsystems.com:443/cae:latest

This uses the volume and maps it to /data inside the container.

The container checks for settings files on startup and uses them to overwrite the ones delivered with the docker image.
