Quick Docker Start

  python3.10 -m venv ~/.venvs/project_name
  source ~/.venvs/{{ project_name }}/bin/activate

  pip install Django==4.2.9

  mkdir ~/project_name

  GN_VERSION=master # Define the branch or tag you want to generate the project from
  django-admin startproject --template=https://github.com/GeoNode/geonode-project/archive/refs/heads/$GN_VERSION.zip -e py,sh,md,rst,json,yml,ini,env,sample,properties -n monitoring-cron -n Dockerfile project_name ~/project_name

  cd ~/project_name
  python create-envfile.py 

The project can also be generated from a local checkout of the goenode-project repository

    git clone https://github.com/GeoNode/geonode-project
    git checkout $GN_VERSION
    django-admin startproject --template=./geonode-project -e py,sh,md,rst,json,yml,ini,env,sample,properties -n monitoring-cron -n Dockerfile project_name ~/project_name

create-envfile.py accepts the following arguments:

• --https: Enable SSL. It's disabled by default
• --env_type:
  • When set to prod DEBUG is disabled and the creation of a valid SSL is requested to Letsencrypt's ACME server
  • When set to test DEBUG is disabled and a test SSL certificate is generated for local testing
  • When set to dev DEBUG is enabled and no SSL certificate is generated
• --hostname: The URL that whill serve GeoNode (localhost by default)
• --email: The administrator's email. Notice that a real email and a valid SMPT configurations are required if --env_type is seto to prod. Letsencrypt uses to email for issuing the SSL certificate
• --geonodepwd: GeoNode's administrator password. A random value is set if left empty
• --geoserverpwd: GeoNode's administrator password. A random value is set if left empty
• --pgpwd: PostgreSQL's administrator password. A random value is set if left empty
• --dbpwd: GeoNode DB user role's password. A random value is set if left empty
• --geodbpwd: GeoNode data DB user role's password. A random value is set if left empty
• --clientid: Client id of Geoserver's GeoNode Oauth2 client. A random value is set if left empty
• --clientsecret: Client secret of Geoserver's GeoNode Oauth2 client. A random value is set if left empty

  docker compose build
  docker compose up -d

Developer Workshop

  http://geonode.org/dev-workshop

Create a custom project

NOTE: You can call your geonode project whatever you like except 'geonode'. Follow the naming conventions for python packages (generally lower case with underscores (_). In the examples below, replace {{ project_name }} with whatever you would like to name your project.

To setup your project follow these instructions:

1. Generate the project

   git clone https://github.com/GeoNode/geonode-project.git -b <your_branch>
   source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
   mkvirtualenv --python=/usr/bin/python3 {{ project_name }}
   pip install Django==3.2.16
   
   django-admin startproject --template=./geonode-project -e py,sh,md,rst,json,yml,ini,env,sample,properties -n monitoring-cron -n Dockerfile {{ project_name }}
   
   cd {{ project_name }}

2. Create the .env file

   An .env file is requird to run the application. It can be created from the .env.sample either manually or with the create-envfile.py script.

   The script accepts several parameters to create the file, in detail:

   • hostname: e.g. master.demo.geonode.org, default localhost
   • https: (boolean), default value is False
   • email: Admin email (this is required if https is set to True since a valid email is required by Letsencrypt certbot)
   • env_type: prod, test or dev. It will set the DEBUG variable to False (prod, test) or True (dev)
   • geonodepwd: GeoNode admin password (required inside the .env)
   • geoserverpwd: Geoserver admin password (required inside the .env)
   • pgpwd: PostgreSQL password (required inside the .env)
   • dbpwd: GeoNode DB user password (required inside the .env)
   • geodbpwd: Geodatabase user password (required inside the .env)
   • clientid: Oauth2 client id (required inside the .env)
   • clientsecret: Oauth2 client secret (required inside the .env)
   • secret key: Django secret key (required inside the .env)
   • sample_file: absolute path to a env_sample file used to create the env_file. If not provided, the one inside the GeoNode project is used.
   • file: absolute path to a json file that contains all the above configuration

   NOTE:

   • if the same configuration is passed in the json file and as an argument, the CLI one will overwrite the one in the JSON file

   • If some value is not provided, a random string is used

     Example USAGE

     python create-envfile.py -f /opt/core/geonode-project/file.json \
       --hostname localhost \
       --https \
       --email [email protected] \
       --geonodepwd gn_password \
       --geoserverpwd gs_password \
       --pgpwd pg_password \
       --dbpwd db_password \
       --geodbpwd _db_password \
       --clientid 12345 \
       --clientsecret abc123 

     Example JSON expected:

     {
       "hostname": "value",
       "https": "value",
       "email": "value",
       "geonodepwd": "value",
       "geoserverpwd": "value",
       "pgpwd": "value",
       "dbpwd": "value",
       "geodbpwd": "value",
       "clientid": "value",
       "clientsecret": "value"
     } 

Start your server

Skip this part if you want to run the project using Docker instead see Start your server using Docker

1. Setup the Python Dependencies

   NOTE: Important: modify your requirements.txt file, by adding the GeoNode branch before continue!

   (see Hints: Configuring requirements.txt)

   cd src
   pip install -r requirements.txt --upgrade
   pip install -e . --upgrade
   
   # Install GDAL Utilities for Python
   pip install pygdal=="`gdal-config --version`.*"
   
   # Dev scripts
   mv ../.override_dev_env.sample ../.override_dev_env
   mv manage_dev.sh.sample manage_dev.sh
   mv paver_dev.sh.sample paver_dev.sh
   
   source ../.override_dev_env
   
   # Using the Default Settings
   sh ./paver_dev.sh reset
   sh ./paver_dev.sh setup
   sh ./paver_dev.sh sync
   sh ./paver_dev.sh start

2. Access GeoNode from browser

   NOTE: default admin user is admin (with pw: admin)

   http://localhost:8000/

Start your server using Docker

You need Docker 1.12 or higher, get the latest stable official release for your platform. Once you have the project configured run the following command from the root folder of the project.

1. Run docker-compose to start it up (get a cup of coffee or tea while you wait)

   docker-compose build --no-cache
   docker-compose up -d

   set COMPOSE_CONVERT_WINDOWS_PATHS=1

   before running docker-compose up

2. Access the site on http://localhost/

Run the instance in development mode

Use dedicated docker-compose files while developing

NOTE: In this example we are going to keep localhost as the target IP for GeoNode

docker-compose -f docker-compose.development.yml -f docker-compose.development.override.yml up

Run the instance on a public site

Preparation of the image (First time only)

NOTE: In this example we are going to publish to the public IP http://123.456.789.111

vim .env
  --> replace localhost with 123.456.789.111 everywhere

Startup the image

docker-compose up --build -d

Stop the Docker Images

docker-compose stop

Fully Wipe-out the Docker Images

WARNING: This will wipe out all the repositories created until now.

NOTE: The images must be stopped first

docker system prune -a

Backup and Restore from Docker Images

Run a Backup

SOURCE_URL=$SOURCE_URL TARGET_URL=$TARGET_URL ./{{project_name}}/br/backup.sh $BKP_FOLDER_NAME

• BKP_FOLDER_NAME: Default value = backup_restore Shared Backup Folder name. The scripts assume it is located on "root" e.g.: /$BKP_FOLDER_NAME/

• SOURCE_URL: Source Server URL, the one generating the "backup" file.

• TARGET_URL: Target Server URL, the one which must be synched.

e.g.:

docker exec -it django4{{project_name}} sh -c 'SOURCE_URL=$SOURCE_URL TARGET_URL=$TARGET_URL ./{{project_name}}/br/backup.sh $BKP_FOLDER_NAME'

Run a Restore

SOURCE_URL=$SOURCE_URL TARGET_URL=$TARGET_URL ./{{project_name}}/br/restore.sh $BKP_FOLDER_NAME

• BKP_FOLDER_NAME: Default value = backup_restore Shared Backup Folder name. The scripts assume it is located on "root" e.g.: /$BKP_FOLDER_NAME/

• SOURCE_URL: Source Server URL, the one generating the "backup" file.

• TARGET_URL: Target Server URL, the one which must be synched.

e.g.:

docker exec -it django4{{project_name}} sh -c 'SOURCE_URL=$SOURCE_URL TARGET_URL=$TARGET_URL ./{{project_name}}/br/restore.sh $BKP_FOLDER_NAME'

Recommended: Track your changes

Step 1. Install Git (for Linux, Mac or Windows).

Step 2. Init git locally and do the first commit:

git init
git add *
git commit -m "Initial Commit"

Step 3. Set up a free account on github or bitbucket and make a copy of the repo there.

Hints: Configuring requirements.txt

You may want to configure your requirements.txt, if you are using additional or custom versions of python packages. For example

Django==3.2.16
git+git://github.com/<your organization>/geonode.git@<your branch>

Increasing PostgreSQL Max connections

In case you need to increase the PostgreSQL Max Connections , you can modify the POSTGRESQL_MAX_CONNECTIONS variable in .env file as below:

POSTGRESQL_MAX_CONNECTIONS=200

In this case PostgreSQL will run accepting 200 maximum connections.

Test project generation and docker-compose build Vagrant usage

Testing with vagrant works like this: What vagrant does:

Starts a vm for test on docker swarm: - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project). - exposes service on localhost port 8888 - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login. - starts, reboots to check if docker services come up correctly after reboot.

vagrant plugin install vagrant-reload
#test things for docker-compose
vagrant up
# check services are up upon reboot
vagrant ssh geonode-compose -c 'docker ps'

Test geonode on http://localhost:8888/

To clean up things and delete the vagrant box:

vagrant destroy -f

Test project generation and Docker swarm build on vagrant

What vagrant does:

Starts a vm for test on docker swarm: - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project). - exposes service on localhost port 8888 - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login. - starts, reboots to check if docker services come up correctly after reboot.

To test on a docker swarm enable vagrant box:

vagrant up
VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant up
# check services are up upon reboot
VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant ssh geonode-compose -c 'docker service ls'

Test geonode on http://localhost:8888/ Again, to clean up things and delete the vagrant box:

VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant destroy -f

for direct deveolpment on geonode-project after first vagrant up to rebuild after changes to project, you can do vagrant reload like this:

vagrant up

What vagrant does (swarm or comnpose cases):

Starts a vm for test on plain docker service with docker-compose: - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project). - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login. - starts, reboots.

[1] to achieve docker-compose build --no-cache just destroy vagrant boxes vagrant destroy -f
