(c) Cisco Systems, Inc + +Building containers and VM images +================================= + +NFVbench is delivered as Docker container which is built using the Dockerfile under the docker directory. +This container includes the following parts: + +- TRex traffic generator +- NFVbench orchestration +- NFVbench test VM (qcow2) + +Versioning +---------- +These 3 parts are versioned independently and the Dockerfile will determine the combination of versions that +are packaged in the container for the version associated to the Dockerfile. + +The NFVbench version is controlled by the git tag that conforms to the semver version (e.g. "3.3.0"). +This tag controls the version of the Dockerfile used for building the container. + +The TRex version is controlled by the TREX_VER variable in Dockerfile (e.g. ENV TREX_VER "v2.56"). +TRex is installed in container from https://trex-tgn.cisco.com/trex/release/ + +The Test VM version is controlled by the VM_IMAGE_VER variable in Dockerfile (e.g. ENV VM_IMAGE_VER "0.8"). +The VM is extracted from google storage (http://artifacts.opnfv.org) + +Updating the VM image +--------------------- + +When the VM image is changed, its version must be increased in order to distinguish from previous image versions. +The version strings to change are located in 2 files: + +- docker/Dockerfile +- nfvbench/nfvbenchvm/dib/build-image.sh + +Building and uploading the VM image +----------------------------------- +The VM image is built and uploaded to Google storage from the CI/CD whenever the +commit text of a gerrit review contains the word "buildvm". + +For details on how this is done, refer to ./jjb/nfvbench/nfvbench.yaml in the opnfv releng repository. + +Building a new NFVbench container image +--------------------------------------- +A new container image can be built and published to Dockerhub by CI/CD by applying a new semver tag to the +nfvbench repository. + + +Workflow summary +---------------- + +NFVbench code has changed: + +- commit with gerrit +- apply a new semver tag to trigger the container image build/publication + +VM code has changed: + +- update VM version in the 2 locations +- commit VM changes with gerrit and add "buildvm" in your commit message to trigger VM build and publish to google storage +- apply a new semver tag to trigger the container image build/publication + +To increase the TRex version: + +- change the Trex version in Dockerfile +- commit with gerrit +- apply a new semver tag to trigger the container image build/publication |
