MySQL 5.5 image doesn't have libmysqlclient-dev package

[DimitriosLisenko]

The images for MySQL 5.6, 5.7, and 8.0 all seem to have the libmysqlclient-dev package present for the specific version of MySQL from the MySQL repository. For example:

# apt-get update > /dev/null && apt-cache policy libmysqlclient-dev
libmysqlclient-dev:
  Installed: (none)
  Candidate: 5.6.51-1debian9
  Version table:
     5.6.51-1debian9 500
        500 http://repo.mysql.com/apt/debian stretch/mysql-5.6 amd64 Packages

However, running the above for the MySQL 5.5 image results in the following:

# apt-get update > /dev/null && apt-cache policy libmysqlclient-dev
libmysqlclient-dev:
  Installed: (none)
  Candidate: (none)
  Version table:

There are some suggestions online to use default-libmysqlclient-dev, but that doesn't seem right to me because that's the one that comes with Debian and is not specific to a MySQL version unlike the others. Also, until recently, it did seem to work for MySQL 5.5 as well. Any suggestions would be appreciated.

Unfortunately MySQL 5.5 has been EOL and unsupported since 98f958b (#566).

The cause of what you're seeing is that for 5.5 we had to download the upstream tarballs instead of installing packages:

mysql/5.5/Dockerfile

Lines 44 to 54 in 3362bac

	&& wget "https://cdn.mysql.com/Downloads/MySQL-$MYSQL_MAJOR/mysql-$MYSQL_VERSION-linux-glibc2.12-x86_64.tar.gz.asc" -O mysql.tar.gz.asc \
	&& apt-get purge -y --auto-remove ca-certificates wget \
	&& export GNUPGHOME="$(mktemp -d)" \
	# gpg: key 5072E1F5: public key "MySQL Release Engineering <mysql-build@oss.oracle.com>" imported

	&& gpg --batch --verify mysql.tar.gz.asc mysql.tar.gz \
	&& gpgconf --kill all \
	&& rm -rf "$GNUPGHOME" mysql.tar.gz.asc \
	&& mkdir /usr/local/mysql \
	&& tar -xzf mysql.tar.gz -C /usr/local/mysql --strip-components=1 \

(So what you're looking for unfortunately wasn't ever part of the 5.5 images. 😞)

Understood, thank you for your response!
