Install the Docker container services using your favorite package manager.
Copy the Dockerfile to a different build directory, to avoid passing the entire wallet directory content to the docker build environment as context.
cp Dockerfile <buildlocation>
cd <buildlocation>
Then build the docker image using the Dockerfile:
docker build .
Tag the build result, naming it 'alastria':
IMGID=`docker images -a | head -2 | tail -1 | awk '{print $3}'`
docker tag $IMGID alastria
The Docker container supplies a shell interface to access the NPM, Angular and Ionic build tools. It also has a default 'init' command that initialises the NPM modules and (tries to) adjust an angular build file as per the README documentation. Run the following command from the wallet repository:
docker run -v <wallet repository>:/data/wallet alastria
This will execute an npm install on the current wallet repository and checkout the alastria-identity subrepository.
Specifying either the npm, ng or ionic build environment will allow you to pass arguments to those build tools. For example, from inside the alastria-wallet repository:
docker run -v `pwd`:/data/wallet alastria npm install
docker run -v `pwd`:/data/wallet alastria ng build --prod --watch
docker run -v `pwd`:/data/wallet alastria ionic cordova build android
The last command will build an Android package that can be installed on an emulator.
The build process takes quite some memory and CPU power. Specify -m 4g to set the docker memory limit to 4Gigabyte. Specify --cpus=2 to allow the use of at least 2 cpus. These are recommended minimum settings for a timely build. Using less than 2Gigabyte will cause the build to fail.
