[multiple] Add role for deploying devscript as SNO

danpawlik · openshift-merge-bot[bot] · commit 6a75aee74e08 · 2026-06-12T14:41:21.000Z
The new role is simply - it just deploy SNO (Single Node OpenShift)
without additional changes.
That role might be useful for developers in daily usage, that might
replace CRC deployment.

+# devscripts_sno
+
+Deploy a Single Node OpenShift (SNO) cluster on libvirt/KVM using the
+[dev-scripts](https://github.com/openshift-metal3/dev-scripts) agent installer
+(`make agent`).
+
+This role is a thin wrapper around the `devscripts` role: it prepares secrets
+and host prerequisites, runs the dev-scripts configuration and host-prep steps,
+executes `make agent`, and copies the resulting kubeconfig to `~/.kube/config`.
+
+It complements the full `devscripts` deployment path (baremetal/libvirt with
+`make all`) and the physical bare metal path documented in
+[bm_sno](../bm_sno/README.md) (`cifmw_bm_sno: true`).
+
+When used from the reproducer, set `cifmw_devscripts_sno: true` so the
+`devscripts` configuration template exports SNO-specific variables (see
+[dev-scripts AGENTS.md](https://github.com/openshift-metal3/dev-scripts/blob/master/AGENTS.md)).
+That flag is separate from including this role by name; reproducer scenarios
+such as `scenarios/reproducers/va-hci-minimal-sno.yml` combine the flag with
+`cifmw_devscripts_config_overrides` for a one-master layout.
+
+## Parameters
+
+### Role-specific
+
+| Parameter | Type | Default | Description |
+| --- | --- | --- | --- |
+| `cifmw_devscripts_sno_installer_timeout` | int | `7200` | Seconds before `make agent` is killed by `timeout` (2 hours) |
+| `cifmw_devscripts_sno_repo_dir` | str | `~/src/github.com/openshift-metal3/dev-scripts` | Path to the dev-scripts repository |
+| `cifmw_devscripts_sno_data_dir` | str | `~/ci-framework-data` | Base directory for CI Framework data on the host |
+| `cifmw_devscripts_sno_artifacts_dir` | str | `{{ cifmw_devscripts_sno_data_dir }}/artifacts` | Directory for role script artifacts and logs |
+
+### Required for standalone use
+
+When running this role outside the reproducer playbook, provide secret content
+(the role writes files from these variables in `pre.yml`):
+
+| Parameter | Description |
+| --- | --- |
+| `cifmw_manage_secrets_citoken_content` | CI token string written to `cifmw_manage_secrets_citoken_file` |
+| `cifmw_manage_secrets_pullsecret_content` | Pull secret JSON written to `cifmw_manage_secrets_pullsecret_file` |
+
+Default secret file paths (from `defaults/main.yml`):
+
+| Parameter | Default |
+| --- | --- |
+| `cifmw_manage_secrets_citoken_file` | `{{ ansible_user_dir }}/secrets/ci_token` |
+| `cifmw_manage_secrets_pullsecret_file` | `{{ ansible_user_dir }}/secrets/pull_secret.json` |
+
+Alternatively, use the file-based variables documented in the
+[devscripts role README](../devscripts/README.md#secrets-management) if you
+integrate with `manage_secrets` directly.
+
+### SNO and dev-scripts configuration
+
+Set `cifmw_devscripts_sno: true` so `conf_ciuser.j2` exports the reduced SNO
+variable set (`NUM_MASTERS=1`, `NUM_WORKERS=0`, and agent-related keys).
+
+Cluster version, networking, and VM sizing are controlled through
+`cifmw_devscripts_config_overrides` (and optional
+`cifmw_devscripts_config_overrides_patch.*` keys), same as the `devscripts`
+role. See [devscripts README](../devscripts/README.md#parameters) and
+[Supported keys in cifmw_devscripts_config_overrides](../devscripts/README.md#supported-keys-in-cifmw_devscripts_config_overrides).
+
+Common SNO overrides (also used in `scenarios/reproducers/va-hci-minimal-sno.yml`):
+
+| Key | Example | Description |
+| --- | --- | --- |
+| `num_masters` | `1` | Single control-plane node |
+| `master_memory` | `16384` | Memory (MiB) for the master VM |
+| `master_disk` | `120` | Root disk size (GiB) |
+| `master_vcpu` | `12` | vCPUs for the master VM |
+| `agent_e2e_test_scenario` | `SNO_IPV4` | Agent installer test scenario |
+| `agent_platform_type` | `none` | Agent platform type |
+| `openshift_version` | `stable-4.18` | OpenShift version (minor or `stable-X.Y`) |
+| `openshift_release_type` | `ga` | Release type (`nightly`, `ga`, `okd`) |
+| `external_subnet_v4` | `192.168.111.0/24` | External network for the cluster |
+| `ip_stack` | `v4` | IP stack (`v4`, `v6`, `v6v4`) |
+
+Additional dev-scripts variables (for example `cifmw_devscripts_cpu_passthrough`,
+`cifmw_devscripts_host_bm_net_ip_addr`) follow the `devscripts` role
+documentation.
+
+## Task files
+
+| Task file | Description |
+| --- | --- |
+| `main.yml` | Orchestrates pre, QEMU ACL, setup, and post phases |
+| `pre.yml` | Maps role vars to `devscripts`, writes secrets, installs packages |
+| `prepare_qemu_home_access.yml` | Installs `acl`/`qemu-kvm` and grants `qemu` traverse on the user home |
+| `setup.yml` | Runs `devscripts` `build_config.yml` and `100_pre.yml`, then `make agent` |
+| `post.yml` | Copies cluster kubeconfig to `~/.kube/config` |
+
+## Examples
+
+### Standalone playbook
+
+See `example-playbook.yaml` in this role directory:
+
+```bash
+ansible-playbook \
+  -e @secrets.yaml \
+  -e @scenarios/reproducers/va-hci-minimal-sno.yml \
+  -i inventory.yaml \
+  roles/devscripts_sno/example-playbook.yaml
+```
+
+Minimal `secrets.yaml` for standalone runs:
+
+```yaml
+cifmw_devscripts_sno: true
+cifmw_manage_secrets_citoken_content: "{{ lookup('env', 'CI_TOKEN') }}"
+cifmw_manage_secrets_pullsecret_content: |
+  {{ lookup('file', lookup('env', 'HOME') ~ '/pull-secret') }}
+
+cifmw_devscripts_config_overrides:
+  openshift_version: "stable-4.18"
+  openshift_release_type: ga
+  num_masters: 1
+  master_memory: 16384
+  master_disk: 120
+  master_vcpu: 12
+  external_subnet_v4: 192.168.111.0/24
+  ip_stack: v4
+  agent_e2e_test_scenario: SNO_IPV4
+  agent_platform_type: none
+```
+
+### Reproducer scenario (libvirt SNO)
+
+From `scenarios/reproducers/va-hci-minimal-sno.yml`:
+
+```yaml
+cifmw_devscripts_sno: true
+cifmw_reproducer_allow_one_ocp: true
+cifmw_devscripts_cpu_passthrough: true
+cifmw_devscripts_host_bm_net_ip_addr: "192.168.111.1"
+
+cifmw_devscripts_config_overrides:
+  num_masters: 1
+  master_memory: 16384
+  master_disk: 120
+  master_vcpu: 12
+  external_subnet_v4: 192.168.111.0/24
+  ip_stack: v4
+  agent_e2e_test_scenario: SNO_IPV4
+  agent_platform_type: none
+  openshift_release_type: ga
+  openshift_version: stable-4.18
+```
+
+After deployment, credentials are under the dev-scripts auth directory:
+
+```bash
+export KUBECONFIG=~/src/github.com/openshift-metal3/dev-scripts/ocp/ocp/auth/kubeconfig
+oc login -u kubeadmin \
+  -p "$(cat ~/src/github.com/openshift-metal3/dev-scripts/ocp/ocp/auth/kubeadmin-password)"
+```
+
+## SNO deployment methods in CI Framework
+
+| Flag | Role / method | Environment |
+| --- | --- | --- |
+| `cifmw_devscripts_sno: true` | dev-scripts agent (`make agent`) on libvirt/KVM | Virtual machine on the hypervisor |
+| `cifmw_bm_sno: true` | `bm_sno` (agent-based, iDRAC Redfish) | Physical bare metal host |
+
+See [reproducer README](../reproducer/README.md#sno-deployment-methods) for how
+these paths fit into full reproducer jobs.
