Replaces the abandoned FelixConfiguration.flowLogsFileEnabled approach (Calico
Enterprise-only field, rejected by OSS v3.26) with the supported primitive:
Calico GlobalNetworkPolicy with `action: Log`.
## Mechanics (verified end-to-end on 2026-05-19)
1. kubectl_manifest applies GNP `wave1-egress-observe-recruiter-responder`
with `namespaceSelector: kubernetes.io/metadata.name == 'recruiter-responder'`,
`types: [Egress]`, `egress: [{action: Log}, {action: Allow}]`.
2. Felix translates to iptables LOG rule in
`cali-po-_ZEv_aILlvyT9fbgWN58` chain with prefix `calico-packet: ` log-level=5.
3. Linux kernel emits LOG entries to ring buffer with transport=kernel.
4. systemd-journald captures kernel transport entries.
5. Alloy DaemonSet ships journal to Loki with `job=node-journal,transport=kernel`.
6. LogQL: `{job="node-journal"} |~ "calico-packet"` returns entries showing
SRC/DST/PROTO/PORT for every NEW egress connection.
## Verified output sample
`calico-packet: IN=cali6cfdec4abc1 OUT=ens18 MAC=... SRC=10.10.122.132
DST=9.9.9.9 LEN=60 TOS=0x00 PREC=0x00 TTL=...`
The Allow rule in the GNP keeps egress functional (recruiter-responder
remained 1/1 Running through the apply — verified Python TCP connections to
1.1.1.1, 8.8.8.8, 9.9.9.9 succeed).
## Wave 1 status
W1.6 observation infra is LIVE for the recruiter-responder pilot. W1.7
remains pending: collect 1 week of `{job="node-journal"} |~ "calico-packet"`
samples, build empirical egress allowlist, flip the GNP rules from
`[Log, Allow]` to `[Allow <specific dests>, Deny]`.
Expand observation to additional namespaces by adding entries to
`spec.namespaceSelector` (e.g. `kubernetes.io/metadata.name in {recruiter-responder,X,Y}`).
