Run OpenStack CPI CI on community Concourse via DevStack on GCP - #338
Merged
Conversation
- add gcp-devstack terraform module: N2 VM (nested-virt) on the bosh-concourse VPC that installs DevStack on boot and applies a SNAT hairpin so shared Concourse workers can reach DevStack floating IPs - add create-devstack/destroy-devstack jobs; run lifecycle/bats in-container on shared workers (drop the openstack worker tag) - resolve the external network by name; serve DevStack over HTTP (no per-run CA) - migrate credentials to community CredHub names; inline deterministic config; single openstack_ci_user credential flowed to the VM via metadata - add wait-for-devstack readiness task; fix concourse_external_network_cidr

WalkthroughThe CI pipeline now provisions DevStack on GCP and runs lifecycle and manual BATS tests through a combined job. Readiness polling and Keystone v3 authentication were added. Terraform creates the DevStack network, VM, routing, and firewall resources. DevStack installation configures OpenStack services, users, quotas, networking, and metadata. CI scripts now use stricter shell handling and local release artifacts. External networks are resolved by name, and integration logging expectations support additional API paths. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- wait-for-devstack: add CI user auth check after Keystone responds, ensuring create_project_and_user has completed before tests start - pipeline: pass OS_USERNAME/PASSWORD/PROJECT to wait-for-devstack task - destroy-devstack: remove passed gate on lifecycle/bats so cleanup always runs; add devstack serial_group to lifecycle and bats jobs - configure.sh: default CONCOURSE_TARGET to bosh (community Concourse)
DevStack Epoxy serves compute at /compute/v2.1/ and Cinder at /volume/v3/ instead of the older /v2.1/ and /v3/ root paths. Update regex patterns to allow an optional path prefix.
- Quote all unquoted variable expansions (SC2086) - Convert maybe_use_custom_ca_ops_file/maybe_load_custom_ca_file to arrays so they expand correctly when empty (SC2086, SC2105 fix) - Remove break from case empty branch — not valid outside loops (SC2105) - Replace echo $(md5sum ...) with direct md5sum invocation (SC2005/SC2046) - Suppress SC1091/SC2154 where dynamic sourcing prevents static analysis
… int output Rename the bats deploy task label from 'deploy' to 'deploy-director' for clarity in the Concourse UI. Redirect bosh int output to a file instead of tee-ing it to stdout to prevent credentials appearing in build logs.
- Use bash indirect expansion (${!name}) instead of eval in optional_value
- Quote all unquoted variable expansions (SC2086)
- Separate local declarations from assignments (SC2155)
- Replace backticks with $(...) (SC2006)
- Use [ -n ] instead of [ ! -z ]
- Replace cat | jq with jq file (UUOC)
- Use export "name=val" pattern in export_terraform_variable
- Remove dead wget+sha1 branch (old_bosh_with_registry_sha1 was never defined)
…lock All OpenStack resources are ephemeral within the DevStack VM, which is destroyed by destroy-devstack regardless of test outcome. The explicit cleanup steps are redundant and add failure surface area.
Add get_params.action: destroy so the post-put get step handles a non-existent workspace instead of erroring.
…ensure Replace separate lifecycle, bats-ubuntu-manual, and destroy-devstack jobs with a single run-devstack-tests job. The outer do: block's ensure always destroys the DevStack VM (wrapped in try: to handle already-gone state), regardless of test success or failure. Also fix GIT_USER_EMAIL in bump-bosh-packages to bots@cloudfoundry.org.
Excon 1.2.8 no longer includes host:port in response log lines, so :\d+ never matches. Remove it; the path-version pattern is sufficient to identify the right log line.
- Merge run-devstack-tests task names to be more descriptive - Fix shellcheck issues in run-lifecycle.sh (SC2086, SC2155, SC2157 bug) - Suppress fog warnings and raise log level to INFO in integration specs - Remove set -x from deploy-manual-networking.sh - Remove POC mentions, timing estimates, internal references from install-devstack.sh, main.tf, and wait-for-devstack.sh

In `@ci/pipeline.yml`:
- Around line 491-497: Update the bosh-openstack-cpi-release resource to use
branch master instead of devstack-gcp-ci, keeping PR-branch testing configurable
outside the committed production pipeline.
- Around line 49-67: Update the run-devstack-tests job so it provisions
gcp-devstack and waits for readiness within each test build, moving those steps
from the upstream create-devstack flow into the job’s do lifecycle; keep
provisioning, test execution, and DevStack destruction together with destruction
retained in ensure.
In `@ci/terraform/ci/bats-manual/bats.tf`:
- Around line 11-13: Set region = var.region_name on the external-network data
source in ci/terraform/ci/bats-manual/bats.tf lines 11-13 and
ci/terraform/ci/lifecycle/lifecycle.tf lines 11-13. Update both
openstack_networking_network_v2.ext lookups so they consistently resolve the
region-specific external network.
In `@ci/terraform/ci/gcp-devstack/install-devstack.sh`:
- Around line 188-201: Update main so readiness authentication is not enabled
until flavors, quotas, image upload, and metadata setup have completed. Add a
final readiness poll after emit_metadata, or split create_project_and_user so
CI-user authentication is enabled only as the last setup step, preserving the
existing operation order otherwise.
- Around line 101-105: The os_admin function in
ci/terraform/ci/gcp-devstack/install-devstack.sh must preserve argument
boundaries by passing arguments as bash -c positional parameters and invoking
openstack with "$@", rather than interpolating $*. In
ci/tasks/wait-for-devstack.sh lines 29-34, construct the Keystone JSON payload
with a JSON encoder such as jq --arg so credential quotes, backslashes, and
control characters remain valid values.

Move the gcp-devstack put and wait-for-devstack task from the former create-devstack job into the run-devstack-tests do block, so provisioning, tests, and teardown are always part of the same build. The outer ensure now covers a leaked VM on provisioning failure too. Remove the try wrapper from the destroy ensure so a failed terraform destroy fails the job visibly rather than silently leaking the GCP VM.

install-devstack.sh: pass os_admin args as bash -c positional parameters so arguments with spaces (e.g. passwords) are not word-split inside the -c string. wait-for-devstack.sh: build the Keystone auth payload with jq --arg so credential values are properly JSON-encoded regardless of their content.

install-devstack.sh: reorder main() so create_project_and_user runs after create_flavors, bump_quotas, and upload_jammy_stemcell. CI-user auth success in wait-for-devstack now means all setup steps have completed, not just user creation. install-devstack.sh: shell-escape ADMIN_PASSWORD with printf %q before writing it into local.conf so passwords with $, backticks, or other metacharacters are not interpreted when stack.sh sources the file.

Ports the OpenStack CPI release pipeline to the community Concourse (
bosh.ci.cloudfoundry.org, teammain). Instead of a persistent external cloud, each run now provisions a disposable, self-contained DevStack on a GCP VM, runs the lifecycle and BATS suites against it, and tears it down.The pipeline already lives here: https://bosh.ci.cloudfoundry.org/teams/main/pipelines/bosh-openstack-cpi
Currently, the full lifecycle is triggered on each merge. The rough cost estimate is:
We can change to manual trigger if needed.
How it works
run-devstack-tests- provisions the DevStack VM via terraform, polls Keystone and CI-user auth until the cloud is fully ready, then runs the lifecycle suite and the manual-networking BATS suite against it. An outerensureblock always destroys the DevStack VM afterwards (on success, failure, or abort), keeping provisioning, tests, and teardown in a single build.Key changes
New infrastructure -
ci/terraform/ci/gcp-devstack/main.tf- an N2 (nested-virt-capable Intel) VM on the communitybosh-concourseVPC:10.100.30.2on a dedicated10.100.30.0/24subnet so the OpenStackauth_urlis stable across runs,can_ip_forward+ an SNAT hairpin rule so Concourse workers can reach DevStack floating IPs off-box,install-devstack.sh- boot startup-script: installs DevStack (stable/2025.1), creates the CI project/user, registers avolumev3alias endpoint for Cinder (fog-openstack compatibility), creates the test flavors, bumps quotas, and applies the SNAT hairpin.versions.tf,.gitignore.Pipeline restructure -
ci/pipeline.ymlrun-devstack-testsjob, which merges the formerlifecycleandbats-ubuntu-manualjobs and owns DevStack provisioning, testing, and teardown end-to-end; a single outerensureguarantees cleanup (a failed destroy fails the job so leaks are visible).pipeline-locatorvanity job, theteardown-directorstep, and thewrite-ca-filestep (DevStack is served over plain HTTP inside the VPC, so there is no CA to manage).tags: [openstack]throughout.Credential & connectivity migration
