Three new vault entries required for Semaphore config-as-code:
- vault_jarvis_ssh_private_key (matches jarvis_ssh_public_key in
group_vars/all/vars; used by Semaphore to SSH to the fleet)
- vault_gitea_deploy_key (existing deploy key on the homelab
repo; used by Semaphore to clone)
- vault_semaphore_api_token (minted from the Semaphore UI; used
by Ansible to drive Semaphore configuration)
These wire up the inputs the upcoming semaphore configure step
will consume.
Quadlet regenerates the systemd unit on daemon-reload but does not
restart the running container — the process keeps its original
environment until restarted. Add explicit 'state: restarted' tasks
gated on the Quadlet template's changed status so env-var updates
actually take effect on re-runs.
The SPA was rendering <base href="https://semaphore.local.mk-labs.cloud/">
regardless of which hostname served the page, causing the imagineering
alias to load the same UI but rewrite all in-page navigation back to the
semaphore hostname. Confusing for users hitting either Traefik alias.
Leave SEMAPHORE_WEB_ROOT empty so Semaphore emits relative URLs and is
fully host-agnostic. Both DNS names (semaphore + imagineering) now serve
cleanly without preference between them.
The template only emits SEMAPHORE_WEB_ROOT when the variable is set, so
the env-var is absent from the container when not needed.
The v2.18 image's entrypoint runs the setup wizard on first boot. Without
the SEMAPHORE_ADMIN_* variables it prompts on stdin, fails with 'Username
cannot be empty', and the container exits — leading to a crash loop.
Set:
SEMAPHORE_ADMIN=admin
SEMAPHORE_ADMIN_NAME=Administrator
SEMAPHORE_ADMIN_EMAIL=admin@local.mk-labs.cloud
SEMAPHORE_ADMIN_PASSWORD={{ vault_semaphore_admin_password }}
SEMAPHORE_PLAYBOOK_PATH=/var/lib/semaphore/playbooks
The env-var bootstrap path is stable in v2.x; only the legacy
'semaphore user add' CLI invocation was unreliable. Drop the manual
user-add step from the README.
Complete rewrite of the semaphore role. Supersedes three prior
iterations whose admin-user-creation logic was unreliable across
Semaphore CLI versions.
Architecture:
- Rootful Podman Quadlet under /etc/containers/systemd/
- Separate PostgreSQL 16-alpine container on a user-defined
podman network (semaphore-net)
- Named volumes for both data stores (semaphore_data,
semaphore_postgres_data) so container recreation is
non-destructive
- Pinned image tags: semaphoreui/semaphore:v2.18.5-ansible2.16.5
and postgres:16-alpine
- Post-deploy HTTP health check fails the playbook if Semaphore
doesn't respond on /api/ping within ~60s
Admin user creation remains intentionally manual after first deploy;
the role README documents the exact podman exec command.
Removes the duplicate deploy_semaphore.yml and the now-unneeded
cleanup_semaphore.yml; day1_deploy_semaphore.yml is the canonical
entry point.
Previous template used inline arithmetic that miscounted the box
width, leaving the right border misaligned on real hostnames. Switch
to computed labels + a fixed inner_width so any hostname / OS string
pads to the same border position.
Introduces a single, idempotent baseline role to supersede the
overlapping day0-baseline and common roles. Capabilities are
feature-flagged so they can be toggled per-host:
- packages (common + OS-family + per-host extras)
- timezone + locale
- chrony time sync against sundial
- baseline users (jarvis admin account with SSH key + NOPASSWD sudo)
- SSH hardening via /etc/ssh/sshd_config.d/ drop-in
- unattended security upgrades (Debian family)
- sysctl drop-in at /etc/sysctl.d/99-mk-labs.conf
- journald retention caps
- branded MOTD
Ubuntu/Debian is first-class; vars/RedHat.yml provides a placeholder
for future distros via the ansible_os_family pattern.
The legacy day0-baseline and common roles remain in place for now and
will be removed during the playbook cleanup sweep, alongside the
existing playbook naming inconsistencies.
- Explicit playbook for removing old container, systemd services, and quadlets
- Optional semaphore_force_clean variable for data removal
- Safer than tags for destructive operations
- Add quadlet tasks and handlers for modern rootless Podman deployment
- Fix broken Jinja in semaphore.container.j2
- Add proper 0777 permissions handling for rootless
- Support semaphore_use_postgres toggle with fallback to legacy BoltDB path
- Parse Host() rules from router definitions
- Supports multiple hostnames per service file (e.g. semaphore + imagineering)
- More robust and future-proof
- Switch podman_container env to SEMAPHORE_DB_DIALECT
- Remove creates: guard on podman generate systemd task
- Add changed_when so unit is always updated on role run
- Updated container quadlet template to use modern SEMAPHORE_DB_DIALECT variable
- Updated env.j2 template for consistency with current SemaphoreUI expectations
- Resolves BoltDB not being honoured on v2.18.x
