docker-nginx VS postgres

Add a brief sleep to the Nginx container's CMD. The default is CMD ["nginx", "-g", "daemon off;"], so something like command: ["sleep", "4", "&&", "nginx", "-g", "daemon off;"]. Didn't try this so not sure whether it'll work or not. Glancing at their docker-entrypoint.sh this will disable autoconfiguration from /docker-entrypoint.d/ (sigh).

A few time ago, I created the this post about nginx official image ENTRYPOINT "issue": https://github.com/nginxinc/docker-nginx/pull/752 .

An alternative to this approach, you could also write a template Dockerfile and then write some shell script that you would run locally to take that template and then write/generate Dockerfiles for each. Many of the official Docker images are setup and built this way. Here is an easy example of the nginx Docker image repository. https://github.com/nginxinc/docker-nginx It has three different templates in the root of the repository and has the update.sh script that is run to take those and write them out to a directory and essentially do a find and replace on the templates in the template. Those generated directories are then committed to the repository and pushed up to be built and published as Docker images.

It's a bit odd to use a custom docker image, rather than the one maintained by nginx Inc though:

https://github.com/signalapp/Signal-TLS-Proxy/blob/main/ngin...

Vs

https://github.com/nginxinc/docker-nginx

For one, this is 5 versions behind (1.18 vs 1.23).

In general seems caddy or haproxy might be a better fit - but nginx is a perfectly fine choice I suppose.

The container image docker.io/library/nginx will hopefully soon have support for socket activation. My PR got merged 9 days ago but the current image does not yet have the funcationality.

} ``` I have fixed the templates at https://github.com/nginxinc/docker-nginx/pull/533

EDIT: Somehow i managed to fix it right now (I struggled with this problem yesterday for hours). This github issue have helped: https://github.com/docker-library/postgres/issues/537 If anyone runs into this problem, those are crucial instructions that helped me: docker system prune docker-compose up --force-recreate --build --remove-orphans --always-recreate-deps --renew-anon-volumes

Tragedy of the commons - only need a few actors to ruin it all for us. Almost all distributors face this problem, from Docker Hub to PyPI. This also reminded me of official Postgres Docker image running a cryptominer in the background [1]

If you open the dockerfile of the desired container, you can determine exactly how and what was built. If not satisfied, you can always build your own container with the right postgresql build flags.

Ok according to The Dockerfile, postgres is running in /var/lib/postgresql/data so you will need enter the container and look at the log files in /var/lib/postgresql/data/pg_log/

I got started on trying to make a basic postgres image but I can't seem to figure out how to include a shell script in the same folder as my nix file (fetched from https://github.com/docker-library/postgres/blob/master/docker-entrypoint.sh and to be modified once I get it working) into the docker image as an entrypoint
