Update Container Config - #144
Conversation
WalkthroughThis pull request updates hub infrastructure configuration. PostgreSQL changes to version 17-alpine in Docker Compose and Kubernetes. Database initialization assigns ownership directly to the keycloak and hub users. Keycloak bootstrap variables use the Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to This change upgrades generated deployments from PostgreSQL 14 to 17 while reusing existing persistent data and changes Kubernetes health checks to use /api/config for liveness and readiness. Without a tested migration and rollback path, existing installations may fail to start or become unavailable, while the health-check change may route traffic to unhealthy pods; merge should wait for these issues to be addressed.

670-676:⚠️ Potential issue | 🟡 MinorPre-existing: duplicate
httpGetkeys in K8s probe definitions.Not introduced by this PR, but worth noting: lines 672 and 675 have duplicate
httpGetkeys in the same object literal. In JavaScript, the last duplicate key wins silently.On line 675 (readinessProbe), the first
httpGet(/q/health/ready) is overwritten by the second (/api/config), so the readiness probe never actually checks the health/ready endpoint.Suggested fix (outside PR scope)
If the intent is to check both endpoints, consider using an
execprobe with a shell command (similar to the Docker Compose hub healthcheck on line 478), or remove the duplicate key.livenessProbe: { - httpGet: {path: '/api/config', port: 8080}, httpGet: {path: '/api/config', port: 8080}, initialDelaySeconds: 10, periodSeconds: 3 + httpGet: {path: '/api/config', port: 8080}, initialDelaySeconds: 10, periodSeconds: 3 }, readinessProbe: { - httpGet: {path: '/q/health/ready', port: 8080}, httpGet: {path: '/api/config', port: 8080}, initialDelaySeconds: 10, periodSeconds: 3 + httpGet: {path: '/q/health/ready', port: 8080}, initialDelaySeconds: 10, periodSeconds: 3 },

object (limits: {cpus: '1.0', memory: '128M'}); increase the memory value to at
least '192M' (preferably '256M') so PostgreSQL and Keycloak migrations won’t get
OOM-killed on first startup—locate the limits: { ..., memory: '128M' } entry in

717-721: Note: PostgreSQL memory settings differ between Compose (128M limit) and K8s (256Mi limit).The K8s config retains a 256Mi limit while Docker Compose was reduced to 128M. This may be intentional, but if the goal is parity between the two deployment modes, consider aligning them. The 32Mi request is low but acceptable since the 256Mi limit provides adequate headroom for bursting.

Just for explanation:
On newer Postgres versions the public schema isn't writable by non-owners. This change makes the user owner of the corresponding DB, rendering the additional GRANT ALL PRIVILEGES obsolete.

The problem was that the object contained the httpGet key twice. I don't know whether this is valid in Kubernetes deployment files, but it is not in JS. The last definition won, therefore the yaml has always just contained this:
httpGet:
path: /api/config
port: 8080Is it really intended to probe two different urls? Then we need a different solution.

cryptomator hub "/api/config" readiness health
💡 Result:
In Cryptomator Hub deployments, the /api/config and health check endpoints are critical for monitoring service readiness and configuration status [1][2][3]. Historically, older versions of Cryptomator Hub utilized port 8080 for both health checks and API requests [3]. However, as of the 1.5.0-beta1 release, the health check functionality was moved to a separate service port, 9000 [3]. To verify service status, common deployment configurations (such as Docker Compose or Kubernetes) use the following endpoints [3]: 1. Health Check Endpoint: Accessed at /q/health/live (typically on port 9000 as of version 1.5.0-beta1+) [3]. 2. Configuration Endpoint: Accessed at /api/config (typically on port 9000 as of version 1.5.0-beta1+) [3]. Example configuration updates for version 1.5.0-beta1 and later: - Docker Compose: The healthcheck test should be updated to point to port 9000: (curl -f http://localhost:9000/q/health/live && curl -f http://localhost:9000/api/config) || exit 1 [3] - Kubernetes: The readiness and startup probes should be updated to use port 9000 [3]: readinessProbe: httpGet: path: /api/config port: 9000 [3] If you encounter errors when accessing /api/config (such as a 500 server error or NullPointerException), it often indicates an issue with service reachability, hostname resolution, or configuration environment variables, such as Keycloak URL mismatches [2][4]. Always ensure that your deployment environment (e.g., Docker, Kubernetes) allows the container to resolve its internal services correctly [2][4].

🌐 Web query:
site:github.com/cryptomator/hub "/api/config" "readinessProbe"
💡 Result:
A readinessProbe is a Kubernetes configuration that periodically checks whether a container is ready to accept network traffic [1][2]. If the probe fails, the container is removed from the service endpoints, meaning it will no longer receive requests until it passes the check again [1][2]. Regarding /api/config, it is not a standard Kubernetes endpoint, but rather a custom application-specific path [3]. Some applications may use /api/config as a custom readiness probe endpoint if the application is considered ready only when its configuration has been successfully loaded or applied [3]. In a Kubernetes manifest, a readinessProbe using such an endpoint would typically be configured as follows: readinessProbe: httpGet: path: /api/config port: 9000 initialDelaySeconds: 10 periodSeconds: 3 If you are encountering issues where a probe is failing unexpectedly, ensure the application is correctly exposing that endpoint on the specified port and that it returns a success status code (typically 200-399) [4]. Always verify your application documentation to confirm the intended use of its specific API endpoints for health checking [3].

Use Hub’s management health endpoints for all probes. When PostgreSQL is unavailable but Hub and Keycloak remain available, /api/config can still return 2xx because ConfigResource.getConfig() does not query the datasource. Kubernetes can therefore keep routing traffic to the pod. Configure the startup, liveness, and readiness probes to use /q/health/started, /q/health/live, and /q/health/ready on management port 9000.
