Add mysql test distribution variant/tag

[ngan]

Hi, we're using this mysql docker image to test Trilogy:

Trilogy is a client library for MySQL-compatible database servers, designed for performance, flexibility, and ease of embedding.

We were interested in using the auth_test_plugin.so plugin to store a user with cleartext password. This allows us to test the enable_cleartext_plugin implementation in our client. Using this plugin would result in the server sending back a cleartext auth switch, which is what we're looking to do. This is so that our client can connect to RDS via IAM credentials.

Would y'all be open to (additionally) building and tagging images using mysql-community-test (instead of mysql-community-server)? This distribution comes with a bunch of test plugins (eg auth_test_plugin.so) whereas the one we're using now doesn't.

For reference, here are the plugins that come with -test:

We have no plans to add variant images that just install different mysql-community-* packages. I'd suggest building your own by extending the current image:

FROM mysql:8.0-debian
RUN set -eux; \
  apt-get update; \
  apt-get install -y mysql-community-test="${MYSQL_VERSION}"; \
  rm -rf /var/lib/apt/lists/*

We try to keep the images as minimal as we can and mysql-community-test and its dependencies is not small:

The following NEW packages will be installed:
   libcommon-sense-perl (3.75-3)
   libjson-perl (4.10000-1)
   libjson-xs-perl (4.030-2+b1)
   libmysqlclient-dev (8.0.36-1debian12)
   libmysqlclient21 (8.0.36-1debian12)
   libtypes-serialiser-perl (1.01-1)
   mysql-client (8.0.36-1debian12)
   mysql-community-server (8.0.36-1debian12)
   mysql-community-test (8.0.36-1debian12)
   psmisc (23.6-1)

Thanks @yosifkit, I have some follow up questions:

1. The pgp key is not available. I'm assuming I have to do this again in my image, is that right?

   # Install key for MySQL APT repository.
   key='BCA4 3417 C3B4 85DD 128E C6D4 B7B3 B788 A8D3 785C'; \
   export GNUPGHOME="$(mktemp -d)"; \
   gpg --batch --keyserver keyserver.ubuntu.com --recv-keys "$key"; \
   mkdir -p /etc/apt/keyrings; \
   gpg --batch --export "$key" > /etc/apt/keyrings/mysql.gpg; \
   gpgconf --kill all; \

2. I'm running into this prompt during build, any way to bypass this?

[yosifkit]

I got the same gpg key error when using mysql:8-debian, but then checked and saw that that tag isn't updated anymore. If I use mysql:8.0-debian, it works fine.

The configuration should only stop the install if apt-get install was run interactively. It seems to work fine in a docker build:

$ DOCKER_BUILDKIT=0 docker build - <<'EOF'
FROM mysql:8.0-debian
RUN set -eux;   apt-get update;   apt-get install -y mysql-community-test="${MYSQL_VERSION}";   rm -rf /var/lib/apt/lists/*
EOF
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
            BuildKit is currently disabled; enable it by removing the DOCKER_BUILDKIT=0
            environment-variable.

Configuring mysql-community-server
----------------------------------

MySQL 8 uses a new authentication based on improved SHA256-based password
methods. It is recommended that all new MySQL Server installations use this
method going forward. This new authentication plugin requires new versions of
connectors and clients, with support for this new authentication method
(caching_sha2_password). Currently MySQL 8 Connectors and community drivers
built with libmysqlclient21 support this new method. Clients built with older
versions of libmysqlclient may not be able to connect to the new server.

To retain compatibility with older client software, the default authentication
plugin can be set to the legacy value (mysql_native_password) This should only
be done if required third-party software has not been updated to work with the
new authentication method. The change will be written to the file
/etc/mysql/mysql.conf.d/default-auth-override.cnf

After installation, the default can be changed by setting the
default_authentication_plugin server setting.

  1. Use Strong Password Encryption (RECOMMENDED)
  2. Use Legacy Authentication Method (Retain MySQL 5.x Compatibility)
Select default authentication plugin

Hm, I’m definitely building it noninteractively and it’s still getting stuck. I noticed you disabled Buildkit. That might be the difference? I’ll test it out, but was there a reason you did that?

[ngan]

Actually, I think I got it to work using:

ARG DEBIAN_FRONTEND=noninteractive

Thanks @yosifkit!

It looks I'm having the key issue for MySQL 5.7 (5.7-debian). Are you guys not pushing to that tag anymore?

#1019

Ok, going back to 8.0. I was able to build the image successfully. However, when I run it, it's just stuck here:

$ docker run --platform linux/x86_64 -e MYSQL_ALLOW_EMPTY_PASSWORD=1 -e MYSQL_DATABASE=test -e MYSQL_HOST=db.local -v ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d --publish 6603:3306 sha256:10bc373754f72c21dc0473c6d72dba876fe243626aabfd0a9d73a27b9669d22d

@yosifkit just curious if you were able to run the image you built?

As a side note, I was able to build 5.7 and it ran successfully.

[ngan]

Closing the loop on this: the problem was that when I installed the mysql-community-test package, it naturally added to the datadir (/var/lib/mysql/). The entrypoint script looks for whether that directory exists and only initializes things if the directory doesn’t exist. This is why the base/original image rm -rf the datadir.

I decided to not do the same thing because I’m wary of other things that might break in the future. Instead, I’m using docker multistage build to install the test package in one layer and copy the auth plugins to the final layer with the non-test package (ie the original docker image).

Thanks for the help, everyone.
