Docker compose

Run docker-compose up from within mojito/docker/ or docker-compose -f docker/docker-compose.yml up from the project directory. It will start Mysql and build/start the Webapp.

In detached mode docker compose up -d. And to remove everything including volumes: docker compose rm -s -v to remove volumes.

To re-use a pre-built image, uncomment the image configuration in docker-compose.yml.

For older version, may need to set some env variable COMPOSE_DOCKER_CLI_BUILD=1 DOCKER_BUILDKIT=1 docker-compose up

To use a local data directory

Create the data directory for mysql: mkdir mojito/docker/.data/db

services:
  db:
    image: mysql:5.7
    volumes:
      - "./.data/db:/var/lib/mysql"

or named volumes

volumes:
  - mojito_mysql
    
services:
  db:
    image: mysql:5.7
    volumes:
      - "mojito_mysql:/var/lib/mysql"

Common issues

208.1 # A fatal error has been detected by the Java Runtime Environment:
208.1 #
208.1 #  SIGSEGV (0xb) at pc=0x00007fffe7f0f4d0, pid=7, tid=22

This is a result of not allocating enough disk space and or memory to the docker environment. Make sure to increase the memory limit and disk usage limit in docker desktop.

Incompatibility Mac/Linux for node/ node_modules/, remove the directories before calling docker commands. Some Dockerfile remove the directories explicitly. (.dockerignore solves this)

One-off build and push

CLI image

Build: docker build -t aurambaj/mojito-cli -f docker/Dockerfile-cli-bk8 . and push: docker push aurambaj/mojito-cli:latest

Example to run a command: docker run --rm --name mojito-cli -it -e MOJITO_HOST="mojito.org" -e MOJITO_PORT="443" -e MOJITO_SCHEME="https" aurambaj/mojito-cli repo-view -n demo1

Webapp image

Build: docker build -t aurambaj/mojito-webapp -f docker/Dockerfile-bk8 . and push: docker push aurambaj/mojito-webapp:latest

Start the webapp: docker run --rm --name mojito-webapp -it aurambaj/mojito-webapp and get a shell to try some command docker exec -it mojito-webapp bash

Old notes

May need extra env variable

Depending on the version of docker DOCKER_BUILDKIT=1 docker build -t aurambaj/mojito-webapp-bk8 -f docker/Dockerfile-bk8 .

Multi-stage build

To build manually docker build -t aurambaj/mojito-webapp-ms8 -f docker/Dockerfile-ms8 .

Create image from already built jars

First build the Webapp with mvn clean install -DskipTests

In the webapp/target directory run docker build -t aurambaj/mojito-webapp-old -f ../src/main/docker/Dockerfile .

To test run it: docker run -p 8080:8080 aurambaj/mojito-webapp-old:latest

Local builds using docker compose

Create a docker image only with the build binaries, and use docker-compose to build locally by mounting the source code and .m2 repository

docker-compose -f docker/docker-compose-build.yml run compile

Depending on the docker installation on Mac

This is not needed with Docker Desktop for Mac but was needed before so for the reccord

Find IP on Mac

Depending on how you instlled docker on Mac, localhost may not work. To get the IP to reach the service: docker-machine ip default.

export l10n_resttemplate_host="192.168.99.111" and then whatever CLI command you have to run, eg. mojito demo-create -n dockertest

Extra configuration for mysql

services:
    db:
    image: mysql:5.7
        user: "1000:50" # needed on Mac
        volumes:
          - "./.data/db:/var/lib/mysql"
        restart: always
        environment:
          MYSQL_ROOT_PASSWORD: ChangeMe
          MYSQL_DATABASE: mojito
          MYSQL_USER: mojito
          MYSQL_PASSWORD: ChangeMe
        command:
          - --character-set-server=utf8mb4
          - --collation-server=utf8mb4_bin
          - --innodb_use_native_aio=0 # needed on Mac

Alpine version

FROM adoptopenjdk:8-jre --> FROM adoptopenjdk/openjdk8:alpine-jre and change to echo -e for script generation and make sure to use /bin/echo for consistent behavior between alpine and ubuntu.
