Flowable

In example/base.py for an app, settings/base.py for a project:

ACTIVITI_HOST = get_env_variable("ACTIVITI_HOST")
ACTIVITI_PASS = get_env_variable("ACTIVITI_PASS")
ACTIVITI_PATH = get_env_variable("ACTIVITI_PATH")
ACTIVITI_PORT = get_env_variable("ACTIVITI_PORT")
ACTIVITI_USER = get_env_variable("ACTIVITI_USER")

Development

If you are using Flowable on Kubernetes, then update your environment variables e.g. https://gitlab.com/kb/workflow/blob/4645-ember-workflow/.env.fish

Testing

If you are using responses to mock Flowable HTTP requests, then add the following to your dev_test.py file:

ACTIVITI_HOST = "localhost"

Add the following to your .env.fish file:

set -x ACTIVITI_HOST (kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
set -x ACTIVITI_PASS "test"
set -x ACTIVITI_PATH ""
set -x ACTIVITI_PORT "8080"
set -x ACTIVITI_USER "rest-admin"

Add the following to your .gitlab-ci.yml file:

test:
  script:
  - export ACTIVITI_HOST=localhost
  - export ACTIVITI_PASS=
  - export ACTIVITI_PATH=
  - export ACTIVITI_PORT=8080
  - export ACTIVITI_USER=

Deploy

To create a Flowable server, start by creating a config/workflow.sls file in your pillar containng the following:

# config/workflow.sls
workflow:
  libreoffice: False

Note

If you are using LibreOffice to convert documents to PDF format, then set libreoffice to True.

Add config.workflow to the top.sls file for your server e.g.

# top.sls
base:
  '*':
    - global.users
  'server':
    - config.workflow

In the salt pillar sls file for your site, add workflow and the activiti_ variables as follows:

sites:
  my_site:
    package: bpm
    profile: django
    workflow: True
    env:
      activiti_host: "localhost"
      activiti_pass: "kermit"
      activiti_path: "flowable-rest"
      activiti_port: "8080"
      activiti_user: "kermit"

To test the deployment on your live server, install httpie in your virtual environment e.g:

# as the 'web' user...
cd ~/repo/project/my_site/live/
source venv/bin/activate
pip install httpie
http GET http://kermit:kermit@localhost:8080/flowable-rest/service/repository/deployments/

You should get a positive response e.g:
