Nginx string interpolation seems to fail in docker-compose.yml about wordpress-nginx-docker-compose HOT 12 CLOSED

Hey, did did you create an .env file with the desired domain?

from wordpress-nginx-docker-compose.

I did indeed. My .env file looks like so:

IP=127.0.0.1
APP_NAME=wpdocker
DOMAIN=wpdocker.local
DB_HOST=mysql
DB_NAME=wpdocker
DB_ROOT_PASSWORD=password
DB_TABLE_PREFIX=wp_

When I docker compose up I receive the following error regarding nginx: invalid number of arguments in "server_name" directive. When I output the string to debug it, ${DOMAIN} is empty

All other values (e.g. APP_NAME) get pulled properly, but in that specific entrypoint: string, variable doesn't get pulled/parsed. Is there, perhaps, something about the entrypoint string that .env vars don't get interpolated?

from wordpress-nginx-docker-compose.

Hm. Strange, haven't had any issues with this. What OS are you on?

from wordpress-nginx-docker-compose.

Still running MacOS Catalina 10.15.7 with Docker Desktop v3.0.3(51017)

from wordpress-nginx-docker-compose.

Interesting. I haven't heard any issues with this and I know many people that use it. But I'll do some investigating

from wordpress-nginx-docker-compose.

Much appreciated. Even performed a fresh pull and still the same thing. Hoping I'm just missing something obvious.

Hey! Can you try this PR i just created?

I think this will work better in more setups.

Do docker-compose rm -v first and then docker-compose up again

from wordpress-nginx-docker-compose.

So, I pulled the PR, reset the container, forced a rebuild, and it still got the same error. However, after adjusting the environment like so, it worked:

environment:
      - NGINX_ENVSUBST_TEMPLATE_SUFFIX=".conf"
      - DOMAIN=${DOMAIN}

Now, I'm receiving a PR_END_OF_FILE_ERROR when attempting to connect over https, and some MySQL connection issues as well. That said, the interpolation-specific issue can be considered resolved. Much appreciated!

from wordpress-nginx-docker-compose.

thanks! Yes, I forgot the dashes in the environment: and it should be = instead of :.

Investigating PR_END_OF_FILE_ERROR further

from wordpress-nginx-docker-compose.

Now this is fixed. I've also fixed the SSL errors and PR_END_OF_FILE_ERROR.

Please test again. I'm merging this later

from wordpress-nginx-docker-compose.

That fixed the SSL issue. I'll take a closer look at the MySQL issue (and perhaps log a more coherent bug) if I get some time in the coming days. Thanks!

from wordpress-nginx-docker-compose.

The PR is is now merged.

Thanks!
