I am trying to build a docker image that is based on centos:systemd. In my Dockerfile I am running a command that depends on systemd running, this fails with the following error:
Failed to get D-Bus connection: Operation not permitted
error: %pre(mod-php-7.1-apache2-zend-server-7.1.7-16.x86_64) scriptlet failed, exit status 1
Error in PREIN scriptlet in rpm package mod-php-7.1-apache2-zend-server-7.1.7-16.x86_64
how can I get the intermediate containers to run with --privileged and mapping -v /sys/fs/cgroup:/sys/fs/cgroup:ro ?
If I comment out the installer and just run the container and manually execute the installer it works fine.
Here is the Dockerfile
FROM centos/systemd
COPY ./ZendServer-9.1.0-RepositoryInstaller-linux.tar.gz /opt
RUN tar -xvf /opt/ZendServer-9.1.0-RepositoryInstaller-linux.tar.gz -C /opt/
RUN /opt/ZendServer-RepositoryInstaller-linux/install_zs.sh 7.1 java --automatic
If your installer needs systemd running, I think you will need to launch a container with the base centos/systemd image, manually run the commands, and then save the result using docker commit. The base image ENTRYPOINT and CMD are not run while child images are getting built, but they do run if you launch a container and make your changes. After manually executing the installer, run docker commit {my_intermediate_container} {my_image}:{my_version}, replacing the bits in curly braces with the container name/hash, your desired image name, and image version.
You might also be able to change your Dockerfile to launch init before running your installer. I am not sure if that will work here in the context of building an image, but that would look like:
FROM centos/systemd
COPY ./ZendServer-9.1.0-RepositoryInstaller-linux.tar.gz /opt
RUN tar -xvf /opt/ZendServer-9.1.0-RepositoryInstaller-linux.tar.gz -C /opt/ \
&& /usr/sbin/init \
&& /opt/ZendServer-RepositoryInstaller-linux/install_zs.sh 7.1 java --automatic
