Embark for Docker

Quick start

In a Bash shell:

source <(curl 'https://raw.githubusercontent.com/embark-framework/embark-docker/master/run.sh')
run_embark demo
cd embark_demo
run_embark

With overrides:

export EMBARK_DOCKER_EXTRA_RUN_OPTS='--rm'
export EMBARK_DOCKER_IMAGE=statusim/embark
export EMBARK_DOCKER_TAG=custom
export EMBARK_DOCKERFILE='https://github.com/embark-framework/embark-docker.git#some/branch'
export EMBARK_VERSION='embark-framework/embark#features/branch'
export NODE_TAG=10.7.0
export RUNNER='https://raw.githubusercontent.com/embark-framework/embark-docker/some/branch/run.sh'

docker build \
       --build-arg EMBARK_VERSION=$EMBARK_VERSION \
       --build-arg NODE_TAG=$NODE_TAG \
       -t $EMBARK_DOCKER_IMAGE:$EMBARK_DOCKER_TAG \
       $EMBARK_DOCKERFILE

source <(curl $RUNNER)
run_embark demo
cd embark_demo
run_embark

Review the Dockerfile and run.sh for all possible overrides.

Shortcuts

The following are equivalent:

run_embark demo

run_embark embark demo

These are also equivlent:

run_embark

run_embark embark run

Other embark commands and non-embark commands should be indicated explicitly:

run_embark embark version

run_embark ps -ef

Updating versions

• Open Dockerfile
• On the ARG directives, update necessary versions.

Building

Building requires Docker to be installed on your local machine.

Scripted

If you have Ruby installed in your system, run:

$ ruby script/build

To release, add --release as a parameter of the build script.

Manually

Building and releasing manually isn't too hard either, but there are a couple steps.

Tags

To facilitate the images being found, we tag them with the following rules (as an example, the 3.1.5 version will be used.)

• Tag with statusim/embark:latest if 3.1.5 is the latest version.
• Tag with statusim/embark:3.1.5
• Tag with statusim/embark:3.1 if 3.1.5 is the highest patch level on 3.1
• Tag with statusim/embark:3 if 3.1.5 is the highest minor and patch level on 3

Generating the image

To generate the image, run:

docker build . -t statusim/embark:<version> [...tags]

Releasing

Releasing requires that you're authenticated to Docker Hub. To do so, run:

$ docker login

Scripted

If you have Ruby installed in your system, run:

$ ruby script/build --release

Manual

Pushing the tags manually implies that the image has been previously built. To push your local images, run:

docker push statusim/embark:version
