Coder added jq to the base image to support mounting secrets from AWS Secrets Manager, or other Kubernetes secrets that are in JSON format. Example:

# Helm values.yaml
coder:
  command:
    - /bin/sh
    - -c     - CODER_PG_CONNECTION_URL=postgresql://coder:$(cat /mnt/postgres-pass/secret.json | jq -r .password)@coder-db.coder.svc.cluster.local:5432/coder /opt/coder server
  volumes:
 - name: "postgres-pass"

Lightweight K8s in Coder Workspaces

Spin up a minimal Kubernetes cluster inside a Coder workspace. Uses k3s with sudo (no systemd).

Limitations

• Containers won't actually run. The OCI runtime fails with unsafe procfs because the workspace itself is a container. Pods stay in ContainerCreating. Fine for Terraform state bugs,

Gateway API HTTPRoute Helm Chart Validation

Tested PR #23501 on a bare kubeadm cluster (arm64, Pi 5, k8s 1.30).

Setup

• Single-node kubeadm cluster with Calico CNI
• Gateway API CRDs v1.2.1 (standard channel)
• Traefik v3 as the Gateway controller (via helm)
