Docker healthcheck failing -- curl not installed? #429

Open robkroll opened 5 years ago

robkroll commented 5 years ago

Hi, trying to start the containers with docker-compose seems to never start the consumer because the healthcheck is failing. I'm new to docker so I'm not really that advanced in how to debug it, but I noticed it was taking a lot of time to start so I commented out the healthcheck and it starts the webserver and consumer both very fast.

If I start a shell on the webserver: docker-compose exec webserver sh

And run the healthcheck command:

/usr/src/paperless/src # curl -f http://localhost:8000
sh: curl: not found

Running apk get to install it works:

/usr/src/paperless/src # apk update && apk add curl
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/community/x86_64/APKINDEX.tar.gz
v3.7.1-29-ge8447864e9 [http://dl-cdn.alpinelinux.org/alpine/v3.7/main]
v3.7.1-28-gb4f049a13b [http://dl-cdn.alpinelinux.org/alpine/v3.7/community]

Executing busybox-1.27.2-r7.trigger
OK: 284 MiB in 120 packages

Then, running curl still doesn't work, it gives a 301 Moved Permanently to /admin/login/ but then doing curl -f http://localhost:8000/admin/login seems to produce some output.

I'm using Docker version 18.06.0-ce, build 0ffa825.

Well that's odd, 'cause the Dockerfile includes an installation of curl. Are you building a custom Docker instance? Here's what happens for me when I use the one on Docker Hub:
