ns8-docuseal

This is a Docuseal module for NethServer 8. To start a new module from it:

Install

Instantiate the module with:

add-module ghcr.io/geniusdynamics/docuseal:latest 1

The output of the command will return the instance name. Output example:

{"module_id": "docuseal1", "image_name": "docuseal", "image_url": "ghcr.io/geniusdynamics/docuseal:latest"}

Configure

Let's assume that the mattermost instance is named docuseal1.

Launch configure-module, by setting the following parameters:

  • host: a fully qualified domain name for the application
  • http2https: enable or disable HTTP to HTTPS redirection (true/false)
  • lets_encrypt: enable or disable Let's Encrypt certificate (true/false)

Example:

api-cli run configure-module --agent module/docuseal1 --data - <<EOF
{
  "host": "docuseal.domain.com",
  "http2https": true,
  "lets_encrypt": false
}
EOF

The above command will:

  • start and configure the docuseal instance
  • configure a virtual host for trafik to access the instance

Get the configuration

You can retrieve the configuration with

api-cli run get-configuration --agent module/docuseal1

Uninstall

To uninstall the instance:

remove-module --no-preserve docuseal1

Update

To Update the instance:

api-cli run update-module --data '{"module_url":"ghcr.io/geniusdynamics/docuseal:latest","instances":["docuseal1"],"force":true}'

Smarthost setting discovery

Some configuration settings, like the smarthost setup, are not part of the configure-module action input: they are discovered by looking at some Redis keys. To ensure the module is always up-to-date with the centralized smarthost setup every time docuseal starts, the command bin/discover-smarthost runs and refreshes the state/smarthost.env file with fresh values from Redis.

Furthermore if smarthost setup is changed when docuseal is already running, the event handler events/smarthost-changed/10reload_services restarts the main module service.

See also the systemd/user/docuseal.service file.

This setting discovery is just an example to understand how the module is expected to work: it can be rewritten or discarded completely.

Debug

some CLI are needed to debug

  • The module runs under an agent that initiate a lot of environment variables (in /home/docuseal1/.config/state), it could be nice to verify them on the root terminal

    runagent -m docuseal1 env

  • you can become runagent for testing scripts and initiate all environment variables

    runagent -m docuseal1

the path become :

    echo $PATH
    /home/docuseal1/.config/bin:/usr/local/agent/pyenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/
  • if you want to debug a container or see environment inside runagent -m docuseal1
podman ps
CONTAINER ID  IMAGE                                      COMMAND               CREATED        STATUS        PORTS                    NAMES

you can see what environment variable is inside the container

podman exec  docuseal-app env
TERM=xterm
container=podman
NGINX_VERSION=1.24.0
PKG_RELEASE=1
NJS_VERSION=0.7.12
NGINX_IMAGE=docker.io/nginx:stable-alpine3.17
CONFIG_DATABASE_URI="postgresql://postgres:Nethesis,[email protected]:5432/toto"
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOME=/root

you can run a shell inside the container

podman exec -ti   docuseal-app sh
/ #

Testing

Test the module using the test-module.sh script:

./test-module.sh <NODE_ADDR> ghcr.io/nethserver/docuseal:latest

The tests are made using Robot Framework
