Thx to both of you, I forgot to add a SOT before the title because yes this is more a Docker question than a Linux one, my bad

I am building a Dockerfile and I am setting up MariaDB repos as follow:

This question is probably way offtopic for a CentOS mailing list.

# Setup MariaDB repos

...

RUN touch /etc/yum.repos.d/MariaDB.repo

What's the right way to do this? The one below?

echo "[mariadb]" >> "/etc/yum.repos.d/MariaDB.repo" echo "name = MariaDB" >> "/etc/yum.repos.d/MariaDB.repo" echo "baseurl = http://yum.mariadb.org/5.5/centos6-amd64" >> "/etc/yum.repos.d/MariaDB.repo" echo "gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB" >> "/etc/yum.repos.d/MariaDB.repo" echo "gpgcheck=1" >> "/etc/yum.repos.d/MariaDB.repo"

You probably want to do a COPY. The Docker docs cover Dockerfile syntax in detail:

https://docs.docker.com/engine/reference/builder/#copy

Yep, this is a much better way to do such things. create the 'MariaDB.repo' in the direstory the 'Dockerfile' resides in, and use the following line in the Dockerfile:

[code] COPY MariaDB.repo /etc/yum.repos.d/MariaDB.repo [/code]

much better that way, for further tips on Dockerfile writing, I'll point you to the offical site "docs.docker.com", esp:

https://docs.docker.com/engine/articles/dockerfile_best-practices/

Have a nice weekend,
