manifest-lock.*.json | Package manifest locks |
builds.json | Build metadata |
meta.json | Build metadata |
# List build artifacts
coreos-tools jenkins builds artifacts <job-name> <build-number>
# Download a specific artifact
coreos-tools jenkins builds artifacts <job-name> <build-number> --download <artifact-name>
# Download to specific path
coreos-tools jenkins builds artifacts <job-name> <build-number> --download <artifact-name> -o /tmp/output.json
Shows what packages changed/upgraded in this build:
coreos-tools jenkins builds diff <job-name> <build-number>
Compare packages between two builds:
coreos-tools jenkins builds diff <job-name> <build1> <build2>
Output format:
{
"build1": 3399,
"build2": 3463,
"stream": "rhel-9.6",
"added": ["new-package-1.0.0.x86_64 (rhel-9.6-baseos)"],
"removed": ["old-package-2.0.0.x86_64 (rhel-9.4-appstream)"],
"changed": [
{
"name": "kernel",
"build1": "kernel-5.14.0-427.112.1.el9_4.x86_64 (rhel-9.4-server-ose-4.17)",
"build2": "kernel-5.14.0-570.94.1.el9_6.x86_64 (rhel-9.6-early-kernel)"
}

# List all changed package names
coreos-tools jenkins builds diff <job-name> <b1> <b2> | jq -r '.changed[].name'
# Show kernel changes specifically
coreos-tools jenkins builds diff <job-name> <b1> <b2> | jq '.changed[] | select(.name == "kernel")'
# Count changes
coreos-tools jenkins builds diff <job-name> <b1> <b2> | jq '{added: (.added | length), removed: (.removed | length), changed: (.changed | length)}'
When cosa version differs between good and bad builds:
# Download cosa git info from both builds
coreos-tools jenkins builds artifacts <job-name> <failed-build> --download coreos-assembler-git.json -o /tmp/failed-cosa.json
coreos-tools jenkins builds artifacts <job-name> <good-build> --download coreos-assembler-git.json -o /tmp/good-cosa.json
# Compare
diff /tmp/good-cosa.json /tmp/failed-cosa.json
# Find commits between versions using GitHub CLI
gh api repos/coreos/coreos-assembler/compare/<old-commit>...<new-commit> \
--jq '.commits[] | {sha: .sha[0:7], date: .commit.author.date, message: .commit.message | split("\n")[0]}'
# Get details of a specific commit
gh api repos/coreos/coreos-assembler/commits/<commit-sha> \
--jq '{sha: .sha, author: .commit.author.name, message: .commit.message}'
