Info

Dockerfiles with RPM build environment for CentOS 6 and 7. Used for automated builds on docker hub.

Both spec files and SRPMs are supported.

Based on official centos image.

Usage

Layout for building from spec files

Place SPECS directory with spec file(s) into some base directory (called <base-dir> below).

If package requires some local (with non-url source) files, place them into <base-dir>/SOURCES/.

Layout for building from SRPMs

Place *.src.rpm somewhere into <base-dir>.

Building

docker run -it --rm -v <base-dir>:/data grossws/makerpm:6 pkg1.spec path/to/srpm/relative/to/<base-dir>/pkg2.src.rpm ...
docker run -it --rm -v <base-dir>:/data grossws/makerpm:7 pkg1.spec path/to/srpm/relative/to/<base-dir>/pkg2.src.rpm ...

Resulting rpms will be stored in <base-dir>/REPO/centos/$releasever/$basearch/ (only x86_64 is supported). SRPMs will be in <base-dir>/REPO/centos/$releasever/SRPMS/ (they are produced only when building from spec).

Packages are built in same order as they appear in command line. Any package can depend on previuos ones.

Dependencies

Dependencies are resolved against standart CentOS repos and EPEL.

To disable EPEL either remove /etc/yum.repos.d/epel.repo file or epel-release package.

To add custom repos just add them to /etc/yum.repos.d/ or install as packages.

Internals

makerpm.sh script:

  • Ensures clean rpmbuild tree for build user (makerpm);
  • Maintains internal temporary repo where all build packages are deployed after build;
  • Creates output layout (like <base-dir>/repo/centos/7/x86_64/);
  • Installs build dependencies for spec/SRPM currently built;
  • Fetches remote sources for package built from spec (using spectool -g -R <pkg.spec>);
  • Builds package (using rpmbuild -ba <pkg.spec> or rpmbuild --rebuild <pkg.src.rpm>);
  • Copies build RPMs and SRPMs to appropriate output dirs and to temporary repo;
  • Invokes createrepo on output dirs.
