nicolaka/netshoot:v0.11 (the pinned tag actually in use) is built on Alpine 3.18.0, where ip6tables is packaged separately from iptables; this image's Dockerfile only installs the latter, so ip6tables does not exist in the container at all (confirmed live: "ip6tables: not found", and against Alpine's own v3.18 package index, not master's). Write 1 to /proc/sys/net/ipv6/conf/all/disable_ipv6 instead - per the kernel's own ip-sysctl docs this is equivalent to also setting conf/default/disable_ipv6 and every existing per-interface disable_ipv6 (lo/eth0/net1) at once, and is strictly stronger than an iptables DROP policy would have been: no IPv6 activity happens on any interface at all, not just filtered output. Needs no capability beyond the NET_ADMIN the guard init container already has. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Secrets
There are two patterns:
*-sealed.yamlfiles are safe to commit and are reconciled by Sealed Secrets.*.shscripts create runtime Secrets from.envdirectly in the cluster.
Use .env.example as the template for local secret names. kubeseal must point
at the in-cluster controller named sealed-secrets-controller in kube-system.
Regenerate committed sealed secrets with the matching script, then commit the resulting YAML. Runtime secret scripts should be run against the target cluster and should not produce committed plaintext.
Certificates
Internal services generally use internal-ca-issuer and home.arpa hostnames.
Public services use Let's Encrypt issuers and nik4nao.com hostnames.
The CA installer lives in core/ca-installer. Its ca-sync CronJob keeps the
served ca.crt and Apple mobileconfig in sync with the cert-manager CA secret.
DNS
Internal DNS records are configured in values/pihole.yaml and
values/pihole-debian.yaml. Add a new hostname to both files when adding a
home.arpa service.
Dashy
core/dashy.yaml defines the deployment and a placeholder ConfigMap. The real
dashboard config comes from config/dashy/conf.yaml:
bash manifests/core/apply-dashy-config.sh
