and wiremock is setup through docker compose like so :

Copy code

wiremock-opensanctions:
    image: public.ecr.aws/s4w6t4b6/wiremock/wiremock:2.32.0
    networks: [pti]
    hostname: wiremock-opensanctions
    restart: unless-stopped
    volumes:
      - ./wiremock/opensanctions:/home/wiremock
    user: "${UGID}"
    command: --proxy-all="<http://localhost:1234>" --record-mappings

I think I know what's going on, the use of

localhost

inside a docker instance, that won't work

Hi @Remi Cartier, yes, localhost would refer to the Docker container’s loopback interface rather than the host’s. You can usually refer to the Docker host via

host.docker.internal

however, so this might be worth trying as your proxy target.
