# KGrid Docker Containers

KGrid Activator can be deployed using docker container architecture.

# Get the docker image ready

The container image for the activator can be either built from the source code or pulled from DockerHub.

# Build from source code

Clone the kgrid-activator repo.

In kgrid activator folder run:

mvn spring-boot:build-image 

This will use the default builder from Spring-boot to build the image.

After this run you will have a local docker image...

~/kgrid-activator $ docker images
REPOSITORY                  TAG                   IMAGE ID            CREATED             SIZE
kgrid/activator             latest                fbe2de94cfa9        3 minutes ago       149MB


You can also specify other builders by adding the option to the maven command; for example -Dspring-boot.build-image.builder=heroku/spring-boot-buildpacks.

# Pull from DockerHub

docker pull kgrid/activator:#.#.#

# Using the Image

Now using the activator image you can create a container name activator from the kgrid/activator image and run it on port 8080...

docker run -p 8080:8080 --name activator kgrid/activator

or mapped to local shelf and running in the background...

docker run -p 8080:8080 -v ${PWD}/shelf:/home/kgrid/shelf --name activator -d kgrid/activator

Once created, you can stop and start the container using docker stop activator and docker start acivator.

# Quick start with docker-compose

You can also start the activator in your environment by setting up docker-compose.yaml file, shown below as an example

version: "3.6"

    container_name: lion-activator
        KGRID_CONFIG: "--kgrid.shelf.cdostore.url=filesystem:file://shelf --cors.url=*  --management.info.git.mode=full"
    image: kgrid/activator:1.5.2
      - 8080:8080
      - "activator_shelf:/home/kgrid/shelf"


that uses the the kgrid/activator:1.5.2 image, with presets for port and shelf.


docker-compose up

# Good to Know

  1. View Container Logs docker logs activator
  2. Start a shell in the container docker exec -it activator sh

# Push New Image

Activator images are stored on DockerHub

docker push kgrid/activator:#.#.#
