How to setup an development setup with NC hub (docker based)

Goal

• have a local setup, where once can change the branches for the NC apps

  • oidc

  • user_oidc

  • integration_openproject

• this allows to have a setup, where one can test or develop against current WIP branches of each of those apps

Context

• we use a docker based setup to reduce any build and run dependencies and simulate the TLS behaviour of a production environment

• this setup is build upon the setup of the Integration OpenProject app

  • we only use the compose files from this repository, so the following steps can easily be amended with an own compose file

Steps

• Pick any location on your system, called $NC_PATH in this guide

# Change to directory and create custom apps subdirectory
cd $NC_PATH
mkdir -p development/custom_apps

# Clone all needed apps
git clone git@github.com:nextcloud/integration_openproject.git
git clone git@github.com:nextcloud/user_oidc.git
git clone git@github.com:H2CK/oidc.git

• go to any repository and switch to the branch you want to run

  • you can switch the branch anytime in future, then the build step needs to be repeated, alongside with setting the correct ownership

• build integration_openproject app

# Change into app directory
cd $NC_PATH/development/custom_apps/integration_openproject

# Run build in node container
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" node:22-alpine npm ci
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" node:22-alpine npm ci

• for the other two apps php and composer are needed besides node and a couple of other dependencies

• build a simple image with all dependencies

• create a Dockerfile with the following code at $BUILD_NC_APPS (again, you need to choose any location on your file system)

FROM composer:2
LABEL authors="openproject"

COPY --from=node:22-alpine /usr/local/bin /usr/local/bin
COPY --from=node:22-alpine /usr/local/lib/node_modules/npm /usr/local/lib/node_modules/npm

RUN npm install -g webpack@5.98.0
RUN npm install -g webpack-cli@6.0.1

RUN apk add rsync

• now build the image with a useful tag - e.g. nextcloud_app_builder:

  • run docker build $BUILD_NC_APPS -t nextcloud_app_builder

• build oidc app

# Change into app directory
cd $NC_PATH/development/custom_apps/oidc

# Ensure you have built the builder image
# Run build in nextcloud_app_builder
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" nextcloud_app_builder make composer
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" nextcloud_app_builder make build

• build user_oidc app

# Change into app directory
cd $NC_PATH/development/custom_apps/user_oidc

# Ensure you have built the builder image
# Run build in nextcloud_app_builder
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" nextcloud_app_builder composer install --no-dev -o
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" nextcloud_app_builder npm ci
docker run -it --rm -v "$(pwd):$(pwd)" -w "$(pwd)" nextcloud_app_builder npm run build

• after build created a lot of new files, we need to change the ownership of all those files to the www-data user group

# Change into custom apps directory
cd $NC_PATH/development/custom_apps

# Run build in nextcloud_app_builder
sudo chgrp www-data . -R
sudo chmod g+w . -R

• now, with all the building done, we need to install and configure our nextcloud instance

• most of this is done from the compose file within the integration_openproject app repo

  • be sure to configure correctly your compose file with the override files

  • this is not part of this guide

# Change into integration app directory
cd $NC_PATH/development/custom_apps/integration_openproject

# Up the stack
docker compose up -d

# Initialize the instance, which can be done usually by
# opening the instance in the browser

# Configure the instance with occ
docker compose exec --user www-data nextcloud php occ config:system:set allow_local_remote_servers --value 1
docker compose exec --user www-data nextcloud php occ security:certificates:import /etc/ssl/certs/ca-certificates.crt

# Enable all apps
docker compose exec --user www-data nextcloud php occ a:e integration_openproject
docker compose exec --user www-data nextcloud php occ a:e user_oidc
docker compose exec --user www-data nextcloud php occ a:e oidc
