Build instructions

This document is aiming to setup single all-in-one dedicated docker container to harbour CordaChecers development environment. It can also be used as a lazy man way of building & running production environmnent.

Create 'corda-prod' container

[luke@BB8 ~]$ docker run -it --name corda-prod ubuntu
root@a9a041421f99:/# exit

[luke@BB8 ~]$ docker start corda-prod
[luke@BB8 ~]$ docker attach corda-prod
root@a9a041421f99:/#

APT

root@a9a041421f99:/ apt update
root@a9a041421f99:/ apt install software-properties-common
root@a9a041421f99:/ apt install nano

Corda CSDE

Java Azul Zulu 11

Template tutorial

Import the Zulu Repository Key for Ubuntu

root@a9a041421f99:~ apt install gnupg

root@a9a041421f99:~ apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0xB1998361219BD9C9

Add Zulu apt Repository

root@a9a041421f99:~ sudo apt-add-repository 'deb http://repos.azulsystems.com/ubuntu stable main'

Install Zulu OpenJDK Version 11 on Ubuntu

root@a9a041421f99:~ apt install zulu-11

root@a9a041421f99:~ java -version

Corda CLI

Official documemtation.

Use python web server to share the CLI binaries

oxbee@MacBook % cd corda-cli-installer-5.0.0.0 
oxbee@MacBook corda-cli-installer-5.0.0.0 % python3 -m http.server

Install WGET on to the 'corda-prpd'

root@a9a041421f99:/ apt-get install wget

Download CordaCli installer onto the 'corda-prod'

root@a9a041421f99:/ cd
root@a9a041421f99:~ ls
root@a9a041421f99:~ pwd

Run the installer

root@a9a041421f99:/%host% install.sh

Add corda-cli.sh to the PATH

  • Creat an alias

    root@BB8:/$ nano ~/.bash_aliases
  + alias corda-cli=${HOME}/.corda/cli/corda-cli.sh
source ~/.bashrc

  • Modifying .bashrc

    nano ~/.bashrc
  + export PATH=~/.corda/cli/:${PATH}
source ~/.bashrc

  • Creating a symlink via ln -s source_file symbolic_link

    root@BB8:~/.corda/cli echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

root@BB8:~/.corda/cli ln -s ~/.corda/cli/corda-cli.sh /usr/local/bin/corda-cli

root@BB8:~/.corda/cli corda-cli -h
Usage: corda-cli [-h] [COMMAND]
-h, -?, -help, --help   Display help and exit.

Docker inside Docker

We need to go deeper ;)

Create an image from a container

docker commit container_id imagename

[luke@BB8 ~]$ docker commit a9a041421f99 corda-cherckers
sha256:bd9e801599214c3e3d4b0cb1884bc94b76f085bbe8fc86fbde42c0077c4cb0ab

[luke@BB8 ~]$ docker image ls
REPOSITORY                 TAG       IMAGE ID       CREATED          SIZE
corda-cherckers            latest    bd9e80159921   23 seconds ago   781MB
gitea/gitea                latest    c24cd4cd2ad5   7 weeks ago      273MB

Mount your host's Docker socket to the container

[luke@BB8 ~]$ docker container rm corda-prod
[luke@BB8 ~]$ docker run -itd --name corda-prod -v /var/run/docker.sock:/var/run/docker.sock corda-cherckers
5676046d2dc2b82472230b3d028ba42aa37e9c5a9aeaaa420c167483beb5abd6

[luke@BB8 ~]$ docker ps
CONTAINER ID   IMAGE                             COMMAND                  CREATED          STATUS                 PORTS     NAMES
5676046d2dc2   corda-cherckers                   "/bin/bash"              10 seconds ago   Up 9 seconds                     corda-prod

[luke@BB8 ~]$ docker exec -it corda-prod /bin/bash
root@5676046d2dc2:/# corda-cli -h
Usage: corda-cli [-h] [COMMAND]
  -h, -?, -help, --help   Display help and exit.

Install Docker

Official documentation. Use apt option. Eventually, you shall be able to run docker command inside container.

root@5babbb69aaa4:/# docker ps
CONTAINER ID   IMAGE                             COMMAND                  CREATED         STATUS                 PORTS     NAMES
5babbb69aaa4   corda-cherckers                   "/bin/bash"              9 minutes ago   Up 9 minutes                     corda-prod
f8cf3e498010   gitea/gitea:latest                "/usr/bin/entrypoint…"   6 weeks ago     Up 2 weeks                       gitea-front-1

Optional

Create corda user that has access to docker and owns the /sources directory.

[!INFO] Password: corda

root@b9a8b2a71d7d:/# groupadd docker
root@b9a8b2a71d7d:/# adduser corda
root@5babbb69aaa4:/# usermod -aG docker corda
root@b9a8b2a71d7d:/# chown corda /sources/

CordaApp

Clone source code repo

It looks that for some reason git was already installed. It is extremely important to have network mode set to HOST.

[luke@BB8 ~]$ docker run -itd --name corda-prod -v /var/run/docker.sock:/var/run/docker.sock -v corda-checkers-src:/sources --network host corda-checkers
b8b724b99be40077455cd57e50919b7baf0c8bb435faef596b07a44dd811e720

luke@BB8 ~]$ docker exec -it corda-prod /bin/bash
root@BB8:/# cd /sources/corda/

root@BB8:/$ cd /sources/
root@BB8:/sources$ git clone https://gitea.djmil.dev/HQLAx/CordaCheckers.git .

Commentout java path in gradle.properties, we have only one java version installed, so it will be used by default:

corda@b9a8b2a71d7d:/sources/corda$ nano gradle.properties

Build & run

oxbee@MacBook backend % ssh luke@bb8
[luke@BB8 ~]$ docker exec -it corda-prod2 /bin/bash
root@BB8:/ cd /source/cord
root@BB8:/ ./gradlew startCorda #run CSDE worker (shall not quit)
root@BB8:/ ./gradlew 5-vNodesSetup # deploy&run your Cordapp

SpringBoot

Aka middleware server.

Java17

Yes, we need two different Java versions for this to work :(

apt-get update
apt install openjdk-17-jdk

Check available java versions:

update-alternatives --config java

or

update-java-alternatives -l

Commit changes to the docker image

Processing triggers for libgdk-pixbuf-2.0-0:amd64 (2.42.8+dfsg-1ubuntu0.2) ...
root@BB8:/# exit
exit

[luke@BB8 ~]$ docker ps
CONTAINER ID   IMAGE                             COMMAND                  CREATED         STATUS                 PORTS     NAMES
eb0679d30d0b   corda-checkers                    "/bin/bash"              3 minutes ago   Up 3 minutes                     corda-prod

[luke@BB8 ~]$ docker commit -m "commit msg" eb0679 corda-checkers

Build & Run

We have to tell gradle where to find proper java version.

root@BB8:/sources/backend> ./gradlew --stop #stop current server
root@BB8:/sources/backend> ./gradlew bootrun -Dorg.gradle.java.home=/usr/lib/jvm/java-17-openjdk-amd64

Frontend

Node.js

Official instructions on how to install latest version.

Download and import the Nodesource GPG key

sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

Create deb repository

NODE_MAJOR=20
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

[!OPTIONAL] NODE_MAJOR can be changed depending on the version you need NODE_MAJOR=16 NODE_MAJOR=18 NODE_MAJOR=20 NODE_MAJOR=21

Run Update and Install

sudo apt-get update
sudo apt-get install nodejs -y

Check the versions

root@BB8:/sources/webapp> nodejs -v
v20.10.0
root@BB8:/sources/webapp> npm -v
10.2.3

NPM

NPM shall be installed by the previous step. And we are going to use SpringBoot to server JS as a set of static resources. So no additional SW installation needed (like npm install -g serve)

Note

At this point, you probably should make another commit to the docker image.

The final size of an image is about 2.2 Gig:

[luke@BB8 ~]$ docker images
REPOSITORY         TAG       IMAGE ID       CREATED          SIZE
corda-checkers     latest    76eddb47d7c5   54 seconds ago   2.16GB

Project dependancies

root@BB8:/sources/webapp> rm -rf build/ node_modules/ package-lock.json
root@BB8:/sources/webapp> npm install

Build and run

Build the release version of frontend

root@BB8:/sources/webapp> npm run build

Copy build directory to the backend

root@BB8:/sources/webapp> cp -r build/* ../backend/src/main/resources/static

You have to restart Springboot in order for changes to take effect.

root@BB8:/sources/backend> ./gradlew --stop
root@BB8:/sources/backend> ./gradlew bootrun -Dorg.gradle.java.home=/usr/lib/jvm/java-17-openjdk-amd64
