MultiPaper Docker images as used in MultiPaper Helm. Contains the latest version of MultiPaper server and master backed by hardened Alpine based OpenJDK images.

• Docker (version 20.10.x and above)
• Kind for testing the images

• Clone the project
• navigate to the project root in your terminal
  To build the dockerfile images locally run the following commands:

# Builds the server
docker build -t multipaper-server -f Dockerfile.server .

# Builds the master
docker build -t multipaper-master -f Dockerfile.master .

Note that in both the dockerfiles you can and should change the version number for the build of multipaper you want to use

# In the server dockerfile
ARG VERSION=1.19.2
ARG BUILD=35

# In the master dockerfile
ARG MULTIPAPER_VERSION=1.19.2
ARG MULTIPAPER_BUILD=35
ARG MASTER_VERSION=2.10.1

The versions must line up with the versions released on the Multipaper Downloads page here: https://multipaper.io/download.html

You will need to setup a local kind cluster to test the images locally, alternatively you can use any other kubernetes enviornment to test them. However other kubernetes enviornments for now is an exercise left for the reader. GLHF.

To load the images into a local Kind cluster

kind load docker-image multipaper-master
kind load docker-image multipaper-server

To run the server clone the helm repository: https://github.com/MultiPaperK8s/MultiPaperHelm and update the image fields in the values.yaml file For example

  image:
    repository: "remcospigot/multipaper-master"
    # Tag of the Docker image to be used.
    # Defaults to the Chart's app version if left blank.
    tag: "2.8.8"
    pullPolicy: IfNotPresent

# The above would be changed to

  image:
    repository: "multipaper-master"
    # Tag of the Docker image to be used.
    # Defaults to the Chart's app version if left blank.
    tag: "latest"
    pullPolicy: IfNotPresent

for the server image section its similar

  image:
    repository: "remcospigot/multipaper"
    # Tag of the Docker image to be used.
    # Defaults to the Chart's app version if left blank.
    tag: "1.18.2-95"
    pullPolicy: IfNotPresent

# Would be changed to

  image:
    repository: "multipaper-server"
    # Tag of the Docker image to be used.
    # Defaults to the Chart's app version if left blank.
    tag: "latest"
    pullPolicy: IfNotPresent

Note that the repository changes must correspond to the -t myCoolDockerBuildName which is the reference kind uses in order to know which image to pull for.

After changing the values.yaml run the helm chart from the root of the https://github.com/MultiPaperK8s/MultiPaperHelm repository.

helm install myCoolReleaseNameHere .
