I am using the provided docker-compose file.
It seems like your mailman-core container isn't able to talk to Postorius on the default dns name, mailman-web, in the provided docker-compose file. These dns names are setup by default if you are using the docker-compose.yaml provided with the repo, but would otherwise needs either changing the value of POSTORIUS_TEMPLATES_BASE_URL or manually setting up the mailman-web DNS in the
/etc/hostof the mailman-core container.
Telnet isn’t included in the container, so I tested with curl:
$ sudo docker exec -it -u mailman mailman-core bash bash-5.0$ grep mailman-web /etc/hosts bash-5.0$ curl http://mailman-web:8000 bash-5.0$
mailman-web does not seem to be in /etc/hosts of mailman-core, but it does resolve and port 8000 is reachable. (I tested with a bad hostname and a different port and did get error messages.) Is there a URL I can pull that will show that it’s working properly?
My original (slightly censored) docker-compose.yaml file is below.
Thanks, Seth
