If you find yourself needing a Debian release which is EOL (and thus only available from [archive.debian.org](http://archive.debian.org)), you should check out [the `debian/eol` image](https://hub.docker.com/r/debian/eol/), which includes tags for Debian releases as far back as Potato (Debian 2.2), the first release to fully utilize APT.

+## Locales
|
|
|
+
|
|
|
+Given that it is a faithful "minbase" install of Debian, this image only includes the `C`, `C.UTF-8`, and `POSIX` locales by default. For most uses requiring a UTF-8 locale, `C.UTF-8` is likely sufficient (`-e LANG=C.UTF-8` or `ENV LANG C.UTF-8`).
|
|
|
+
|
|
|
+For uses where that is not sufficient, other locales can be installed/generated via the `locales` package. [PostgreSQL has a good example of doing so](https://github.com/docker-library/postgres/blob/69bc540ecfffecce72d49fa7e4a46680350037f9/9.6/Dockerfile#L21-L24), copied below:
|
|
|
+
|
|
|
+```dockerfile
|
|
|
+RUN apt-get update && apt-get install -y locales && rm -rf /var/lib/apt/lists/* \
|
|
|
+ && localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
|
|
|
+ENV LANG en_US.utf8
|
|
|
+```
