Packages systemd versus systemd-container

Issue

• We are building and deploying two applications with strategy docker based on a rhel7 image, registry.access.redhat.com/rhel7:latest.

• For the first application, we need:

yum -y install httpd

• For the second:

yum install -y glibc nss-softokn-freebl libX11 libxcb libXau zlib libXext fontconfig expat freetype libSM libICE libuuid libXrandr libXrender libXinerama

• The package httpd and one of the second packages depends on systemd and systemd-libs.

  • We are getting package conflicts for both applications with systemd and systemd-libs versus systemd-container and systemd-container-libs.

• I could overcome the issue by doing:

yum -y swap -- remove systemd-container systemd-container-libs -- install systemd systemd-libs

• Can you tell us as to what is happening exaclty ?

• Questions:

  • I found something like fakesystemd as well. Does systemd-container replace fakesystemd?
  • I found this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1209640. Do we have an issue in the same corner and will it be resolved when this issue is resolved?
  • Is it a good idea to swap systemd-container by systemd? Can we expect other issues doing so?
  • Is there a better solution/workaround?
