RPM Spec for Consul and Consul-Template

Tries to follow the packaging guidelines from Fedora.

• Binary: /usr/bin/consul
• Config: /etc/consul.d/
• Shared state: /var/lib/consul/
• Sysconfig: /etc/sysconfig/consul
• WebUI: /usr/share/consul/

Versioning

The version number is hardcoded into the SPEC, however should you so choose, it can be set explicitly by passing an argument to rpmbuild directly:

$ rpmbuild --define "_version 0.8.10"

Build

• Build the Docker image. You can pick and choose the RHEL version.

  docker build --rm -t consul:build7 -f Dockerfile.centos7 .
  

  or

  docker build --rm -t consul:build6 -f Dockerfile.centos6 .
  

• Run the build. Replace # with the RHEL version you want.

  docker run --rm -v $PWD:/build consul:build#
  

• Retrieve the built S/RPMs from:

  • $PWD/rpmbuild/RPMS
  • $PWD/rpmbuild/SRPMS

Result

Three RPMs:

• consul server
• consul web UI
• consul-template

Run

• Install the RPM.
• Put config files in /etc/consul.d/.
• Change command line arguments to consul in /etc/sysconfig/consul.
  • Add -bootstrap only if this is the first server and instance.
• Start the service and tail the logs systemctl start consul.service and journalctl -f.
  • To enable at reboot systemctl enable consul.service.
• Consul may complain about the GOMAXPROCS setting. This is safe to ignore; however, the warning can be supressed by uncommenting the appropriate line in /etc/sysconfig/consul.

Config

Config files are loaded in lexical order from the /etc/consul.d/. Some sample configs are provided.
