Write Content To File From Dockerfile And/or Any Other Method
I am building a Dockerfile and I am setting up MariaDB repos as follow:
# Setup MariaDB repos RUN touch /etc/yum.repos.d/MariaDB.repo
I should write this inside the MariaDB.repo file:
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/CentOS6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
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”

This question is probably way offtopic for a CentOS mailing list.
You probably want to do a COPY. The Docker docs cover Dockerfile syntax in detail:

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/

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
