So you got WebSphere Liberty Container image based on Ubuntu from here.
And you'd like to change locale because you'd like to have logs in another language, such as Japanese, etc.
My procedure in this post is based on this but I think you need some additional steps, so here is how.
By the way my environment is MacOS Monterey 23.6.5, Apple M1Pro,using podman instead of docker. That's why I pulled amd64, of course you can get other architecture images depending on your environment.
1.Make Containerfile to install JP locale package and set environment variables with root.
FROM docker.io/amd64/websphere-liberty:23.0.0.3-full-java17-openj9
USER 0
RUN apt-get update \
&& apt-get install -y language-pack-ja \
&& rm -rf /var/lib/apt/lists/*
ENV LANG=ja_JP.UTF-8 \
LANGUAGE=ja_JP:ja \
LC_ALL=ja_JP.UTF-8 \
TZ="Asia/Tokyo"
USER 1001
2.Build image.
$ podman build -t amd64-websphere-liberty:23.0.0.3-full-java17-openj9-jp .
