This page lists the available Docker images that have been preconfigured with third-party build tools such as C and Golang compilers, autoconf, make, etc.; and third-party open-source libraries such as NNG. Image configuration is maintained by files in the "ci-management" Gerrit repository: https://gerrit.o-ran-sc.org/r/gitweb?p=ci-management.git;a=tree;f=docker
These base builder images help meet the following goals:
- Use exactly the same version of third-party libraries by all components. Initially the most important library is NNG.
- Reduce Jenkins build time by avoiding repeats of third-party package installs. Remember that a verify build is performed for every change published to https://gerrit.o-ran-sc.org
Most base images do not have any RIC libraries or software preinstalled. RIC project libraries such as RMr, mdclog, asn1 are published to PackageCloud as binary packages (deb or rpm as appropriate) and installed during the build process. However, PackageCloud does not yet support Alpine packages (.apk).
Projects can use these images in a Dockerfile "FROM" command in the docker build process. For example, to use the Ubuntu 18 base image (see below for the current tag):
FROM nexus3.o-ran-sc.org:10004/bldr-ubuntu18-c-go:CURRENT-TAG-HERE AS project-build
The base images are pushed to the LF docker "staging" registry nexus3.o-ran-sc.org:10004 and refreshed daily. This registry allows regular builds so that the RIC base images keep up with changes in their respective base images. Browse the available images here: O-RAN-SC Nexus Registry But note that only one image is kept and THE IMAGE TAGS CHANGE FREQUENTLY as the contents are extended with new packages. If your build stops working, use the link below to find the latest tag and switch to that.
If your team depends on these images, please add yourself as a watcher to this page by clicking on the WATCHING link at the top/right!
