### Running JOSM in the dev stack
-- Run JOSM with FMTM:
+- Run JOSM with FMTM via Just:
```bash
-docker compose \
- -f docker-compose.yml \
- -f contrib/josm/docker-compose.yml \
- up -d
+just start josm
```
This adds JOSM to the docker compose stack for local development.
-Access the JOSM Remote API:
-Access the JOSM GUI in browser:
You can now call the JOSM API from FMTM and changes will be reflected in the GUI.
-### Debugging local FMTM on mobile
+### Debugging local services on mobile
- It's difficult to debug services running on localhost from your mobile phone.
- An easy way to do this is by tunneling: Cloudflare provides a great free
solution for this (an alternative is Ngrok).
-- To run the tunnel to the FMTM API:
-
- ```bash
- docker compose \
- -f docker-compose.yml \
- -f contrib/tunnel/fmtm/docker-compose.yml \
- up -d
- ```
-
-- View the website to access FMTM remotely (e.g. via mobile):
-
- ```bash
- docker compose \
- -f docker-compose.yml \
- -f contrib/tunnel/fmtm/docker-compose.yml \
- logs fmtm-tunnel
- ```
-
-- Now the final step is to add the provided tunnel URL to the allowed CORS
- origins on API startup:
-
- ```bash
- EXTRA_CORS_ORIGINS=https://the-url-you-were-given.trycloudflare.com \
- docker compose restart api
- ```
-
-### Using local ODK Central on mobile
-
-- Sometimes you wish to use a project in your local ODK Central, via ODK Collect
- on your mobile.
-- To run the tunnel to the ODK Central API:
-
- ```bash
- docker compose \
- -f docker-compose.yml \
- -f contrib/tunnel/odk/docker-compose.yml \
- up -d
- ```
-
-- View the website to access ODK Central remotely (e.g. via mobile):
-
- ```bash
- docker compose \
- -f docker-compose.yml \
- -f contrib/tunnel/odk/docker-compose.yml \
- logs central-tunnel
- ```
-
-1. Requirement: Restart ODK Central using the domain override
- (required for form download URLs):
-
- ```bash
- CENTRAL_DOMAIN_OVERRIDE=the-domain-without-protocol.trycloudflare.com \
- docker compose restart central
- ```
+- We may also wish to debug our local ODK Central instance forms on our mobile ODK
+ Collect.
+- To handle both of these instances set up tunnels for all services with:
+
+```bash
+just start tunnel
+```
+
+To complete this setup, two additional steps must be complete:
+
+- **Requirement 1**: For login to work, use the temporary login.
