Move to new OpenStack version in StarlingX¶

This section describes how to move from OpenStack Stein to OpenStack Train in StarlingX.

Introduction ¶

When you apply the OpenStack application in StarlingX, the following OpenStack services are launched in containers:

stx-keystone
stx-nova
stx-neutron
stx-horizon
stx-placement
stx-cinder
stx-glance
stx-aodh
stx-ironic
stx-panko
stx-barbican
stx-ceilometer
stx-heat

Moving to a new OpenStack release in StarlingX applies updates to the already installed OpenStack services. The examples in this section show the upgrade from OpenStack Stein to OpenStack Train.

OpenStack Train upgrade patches ¶

The following patches are included in the upgrade to OpenStack Train.

OpenStack service upgrade¶

OpenStack-helm & OpenStack-helm-infra RPM upgrade¶

Note

There is no tag for this 2-project release. You will need to select the latest commit.

Upgrade to OpenStack Train ¶

Update targeted branch/version¶

Update the targeted branch/version in the directives files for each project.

Update the cgcs-root/stx/upstream/openstack/python-nova/centos/stx-nova.dev_docker_image file:

BUILDER=loci
LABEL=stx-nova
PROJECT=nova
PROJECT_REPO=https://opendev.org/openstack/nova.git
PIP_PACKAGES="pycrypto httplib2 pylint python-ironicclient"
DIST_PACKAGES="openssh-clients openssh-server libvirt e2fsprogs"
PROFILES="fluent nova ceph linuxbridge openvswitch configdrive qemu apache"
CUSTOMIZATION="yum install -y openssh-clients"

Update the cgcs-root/stx/upstream/openstack/python-nova/centos/stx-nova.stable_docker_image file:

BUILDER=loci
LABEL=stx-nova
PROJECT=nova
PROJECT_REPO=https://opendev.org/openstack/nova.git
PROJECT_REF=stable/train
PIP_PACKAGES="pycrypto httplib2 pylint python-ironicclient"
DIST_PACKAGES="openssh-clients openssh-server libvirt e2fsprogs"
PROFILES="fluent nova ceph linuxbridge openvswitch configdrive qemu apache"
CUSTOMIZATION="yum install -y openssh-clients"

Build wheels for specific OpenStack version¶

Change the release in ${MY_REPO}//build-tools/build-wheels/build-wheel-tarball.sh:
```
CURRENT_STABLE_OPENSTACK=train
```

Use the following script to get specific version information for dependent packages:

https://raw.githubusercontent.com/openstack/requirements/stable/train/upper-constraints.txt

Update the build-tools/build-wheels/docker/stable-wheels.cfg file with the related entries, as shown below:

django_floppyforms-1.7.0-py2.py3-none-any.whl|tar|https://files.pythonhosted.org/packages/8c/18/30a9137c7ae279a27ccdeb10f6fe8be18ee98551d01ec030b6cfe8b2d2e2/django-floppyforms-1.7.0.tar.gz|django-floppyforms-1.7.0

Build wheels with the following command:

export OS=centos
export BUILD_STREAM=stable
export MY_REPO=/home/wrsroot/starlingx/workspace/localdisk/designer/wrsroot/starlingx/cgcs-root/
export MY_WORKSPACE=/home/wrsroot/starlingx/workspace/localdisk/loadbuild/wrsroot/starlingx/
${MY_REPO}//build-tools/build-wheels/build-wheel-tarball.sh \
--os ${OS} \
--stream ${BUILD_STREAM}

Build Docker images for OpenStack¶

Build Docker images with the following command:

export OS=centos
export BUILD_STREAM=stable
export MY_REPO=/home/wrsroot/starlingx/workspace/localdisk/designer/wrsroot/starlingx/cgcs-root/
export MY_WORKSPACE=/home/wrsroot/starlingx/workspace/localdisk/loadbuild/wrsroot/starlingx/
export BRANCH=master
export CENTOS_BASE=starlingx/stx-centos:${BRANCH}-${BUILD_STREAM}-latest
export WHEELS=https://mirror.starlingx.windriver.com/mirror/starlingx/master/centos/latest_docker_image_build/outputs/wheels/stx-centos-stable-wheels.tar
time $MY_REPO/build-tools/build-docker-images/build-stx-images.sh \
--os centos \
--stream ${BUILD_STREAM} \
--base ${CENTOS_BASE} \
--wheels ${WHEELS} \
--latest \
--only  $1    //stx-nova,stx-horizon

For additional information on building Docker images, refer to the StarlingX wiki entry for Building Images

Tag and push image to Docker registry¶

First tag and push your new image to docker.io. Then tag and push to your local registry for verification. For example:

docker images
root/stx-horizon         dev-centos-stable-build    ccce6df31a58   30 minutes ago      868MB
docker tag ccce6df31a58  username/stx-horizon:dev-centos-stable-train
docker push username/stx-heat:dev-centos-stable-train    // push to docker.io

Update manifest.yaml¶

You will need to update the manifest.yaml file for the OpenStack upgrade.

The exact updates needed are determined on a case-by-case basis.

Please refer to this patch: https://review.opendev.org/#/c/684166

Test and debug¶

Here are some tips for testing and debugging your upgrade:

Refer to the StarlingX wiki entry for general container and debugging info.
You will need to create a test patch to perform pre-merge verification of your test image. For example: https://review.opendev.org/#/c/688025

Use system application management commands to manage the application. For example:

system application-upload -n stx-openstack stx-openstack-1.0-16.tgz
system application-apply stx-openstack
system application-remove stx-openstack
system application-delete stx-openstack
watch -n 5 system application-list

Use kubectl commands for log analysis. For example:

tail -f /var/log/sysinv.log
tail -f /var/log/armada/stx-openstack-apply.log
kubectl -n openstack get po
kubectl -n openstack logs nova-compute-compute-0-75ea0372-nmtz2
kubectl -n openstack exec -it nova-compute-compute-0-31b0f4b3-2rqgf -- bash
kubectl -n openstack describe pod nova-compute-compute-0-31b0f4b3-2rqgf
kubectl -n openstack get pod nova-compute-compute-0-31b0f4b3-2rqgf -o yaml
/var/log/container/*.log  //To see related pod logs for issue debug
