CORS not working properly for stac-fastapi with stac-browser

[ianhorn]

Problem description

All the API urls work when I start the containers. I'm even able to access the http://:8081/api.html; however, the STAC-Browser still says I don't have CORS-enabled for 8081.

Expected Output

I added the following to the environment for the fastapi. I removed my ec2 dns

      - CORS_ALLOW_ORIGINS=*
      - CORS_ALLOW_METHODS=GET, POST, PUT, DELETE
      - CORS_ALLOW_HEADERS=Content-Type,Authorization
      - ALLOWED_ORIGINS=*
      - CORS_ORIGINS=*
      - CORS_ORIGINS=<http://ec2DNS>:8085,*
      - API_URL=http://<ec2dns>:8081

Environment Information

EC2 - AMI Amazon Linux 2023
Docker

It depends on your stac-fastapi-pgstac version, the CORS configuration by env variable is available just from 3.0.1 https://github.com/stac-utils/stac-fastapi-pgstac/blob/main/CHANGES.md#301---2024-11-14

Thanks for your response. I updated the image verison for the docker-compose. All the urls work fine still, but now when I open up http://dns:8085 all I see is the title and white page and it's just loading. No console errors or anything. The stac api endpoint still says cors error in radiant earth's stac-browser.

I'm just going to back to using the stac-fastapi-pgstac repo because it was working fine. Maybe I'll try to add the titiler and then stac-browser to that docker-compose.yml.

Thanks again for your help. These are beautiful tools.

I'm also having some problems with the local stac-browser. I'm using stac-fastapi-pgstac:4.0.1 with the cors origin and method env vars.

  - CORS_ORIGINS=*
  - CORS_METHODS=GET,POST,OPTIONS

whenever i try to open the catalog in the local browser i got the CORS header message, but if i use localhost:8081 on radiantearth stac-browser i don't have any problem opening it

I believe the issue is unrelated to CORS. What I believe is going on is my API url is a domain name, but the links are still getting created as localhost. Stac-browser does does not like the mixing of the two.

Is there somewhere in the docker-compose.yml to set the API url?
