NS8 Applications that need 2 urls(frontend, backend)

Development
1

I have an application that needs 2 url for frontend and backend server(API) server.

Example:

for this we need 3 urls:


# dns settings
APP_HOST=rmm.example.com
API_HOST=api.example.com
MESH_HOST=mesh.example.com

How can i handle the configurations for all this 3 urls.
For mesh central we can use an external Meshcentral server made by @mrmarkuz .

Any ways to handle and on top use a proxy manager such as traefik or nginx

In build-images.sh you can allocate ports, see also Port allocation | NS8 dev manual

For example in mattermost 2 TCP ports are allocated:

Set an env variable to an allocated port:

In your case you need create 3 traefik http routes, example for 1 route:

So for my case i will have


response = agent.tasks.run(
              agent_id=agent.resolve_agent_id('traefik@node'),
              action='set-route',
              data={
                  'instance': os.environ['MODULE_ID'],
                  'url':  'http://127.0.0.1:' + os.environ["TCP_PORT"],
                  'host': host,
                  'http2https': h2hs,
                  'lets_encrypt': le
              },
          )
response = agent.tasks.run(
              agent_id=agent.resolve_agent_id('traefik@node'),
              action='set-route',
              data={
                  'instance': os.environ['MODULE_ID'],
                  'url':  'http://127.0.0.1:' + os.environ["API_TCP_PORT"],
                  'host': host,
                  'http2https': h2hs,
                  'lets_encrypt': le
              },
          )

something like this
and what of registering the url in traefik eg:

agent.set_env("TRAEFIK_HOST", host)

This just sets the environment variable TRAEFIK_HOST to the host variable.

For example to set the http route for apihost:

apihost = data.get("apihost")
agent.set_env("API_HOST", apihost)
response = agent.tasks.run(
              agent_id=agent.resolve_agent_id('traefik@node'),
              action='set-route',
              data={
                  'instance': os.environ['MODULE_ID'],
                  'url':  'http://127.0.0.1:' + os.environ["API_TCP_PORT"],
                  'host': apihost,
                  'http2https': h2hs,
                  'lets_encrypt': le
              },
          )
