Problems installing MongoDB in a docker container

Ksortakh_Kraxthar · December 15, 2020, 1:06pm

So, I have a Dockerfile for a container containing MongoDB:

FROM ubuntu:20.04

RUN apt update
RUN apt-get install -y wget
RUN apt-get install -y software-properties-common

RUN wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | apt-key add -
RUN echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-4.2.list
RUN apt update
RUN apt-get install -y mongodb-org

EXPOSE 27017

CMD /usr/bin/mongod

The problem is that when trying to build, I get the error

(...)

I recently had a somewhat similar problem asked in Problems installing MongoDB in a container regarding something similar with Singularity.
In there, the solution was to upgrade to Ubuntu 20.04, however in this case this is already done.

Note that I also get three other errors/warnings along the way:

Warning: apt-key output should not be parsed (stdout is not a terminal)

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

debconf: delaying package configuration, since apt-utils is not installed

But as far as I read those are harmless, including the last one (see docker - Avoid apt-utils warning in Debian Dockerfile - Server Fault).

When I separately install the server part itself using

RUN apt-get install -y mongodb-org-server

I get

Setting up mongodb-org-server (4.2.11) ...
Adding system user `mongodb' (UID 105) ...
Adding new user `mongodb' (UID 105) with group `nogroup' ...

Hi @Ksortakh_Kraxthar

In the main you have already been answered on this topic Connection error when running MongoDB inside a container: connection refused - #2 by chris

You seem intent on rolling your own, look at the dockerfile linked in that post for inspiration.

Your next issue beyond that is one of platform compatibility. Look here for mongodb 4.2

Main reason I use my own is that it’s kind of a MCVE. I tend to switch working environment a lot. But using the code in there is fine with me.

So I took the full code mongo/Dockerfile at master · docker-library/mongo · GitHub and tried to get it to work (without any alteration), sadly what I get is

I still don’t understand how the official image does not suffice, even as a base.

That is a gpg ipv6 issue.

It suffices, just saying why I didn’t do it at first.

Added your lines, still the same error:

I’m also reading that gpg keyservers are flaky, yes they are. So some retries might be needed.

Or do the “bad” thing and do what you had for your previous Dockerfile:
RUN wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | apt-key add -

Ksortakh_Kraxthar · December 17, 2020, 1:32pm

Couldn’t get it to work in any configuration.
Tested out some other official dockerfiles from the github, couldn’t build any of them.
Instead I switched to using bitnami/mongodb:latest directly, that works.
