+## Issue
+
+A workload needs to pull container images from more than one private registry (for example a public mirror, a vendor registry, and a team-internal Harbor). Each registry exposes its own credentials in a separate `~/.docker/config.json`-style file. Kubernetes accepts only one `imagePullSecrets` entry at a time per ServiceAccount default, and even when several are listed, supplying many secrets adds operational noise.
+
+This article describes how to merge two or more existing pull-secret JSON files into a single `kubernetes.io/dockerconfigjson` Secret that satisfies every registry in one step.
+
+## Root Cause
+
+The `dockerconfigjson` Secret type is a plain base64-wrapped copy of a JSON document with the shape:
+
+```json
+{
+  "auths": {
+    "registry-a.example.com": { "auth": "<base64>" },
+    "registry-b.example.com": { "auth": "<base64>" }
+  }
+}
+```
+
+When two pull-secret files contain disjoint `auths` keys, merging is purely a JSON union — the kubelet image puller looks up the registry hostname at pull time, and any matching entry under `auths` is used. The work is therefore client-side text manipulation; no API change is needed.
+
+## Resolution
+
+### Steps
+
+1. Export each existing pull secret to a plain JSON file. For a Secret that already lives in the cluster:
+
+   ```bash
+   kubectl get secret registry-a-pull -n team-x \
+     -o jsonpath='{.data.\.dockerconfigjson}' | base64 -d > /tmp/auth-a.json
+
+   kubectl get secret registry-b-pull -n team-x \
+     -o jsonpath='{.data.\.dockerconfigjson}' | base64 -d > /tmp/auth-b.json
+   ```
+
+   For a `~/.docker/config.json` produced by `docker login`, copy the file verbatim.
+
+2. Merge the `.auths` objects with `jq`. The right-hand operand wins on key collisions, so put the higher-priority registry second if the same host appears in both:
+
+   ```bash
+   jq -s '.[0] * .[1] | {auths: .auths}' /tmp/auth-a.json /tmp/auth-b.json \
+     > /tmp/auth-merged.json
+   ```
+
+   Inspect:
+
+   ```bash
+   jq '.auths | keys' /tmp/auth-merged.json
+   ```
+
+3. Create or replace the merged Secret:
+
+   ```bash
+   kubectl create secret generic glean-merged-pull \
+     --from-file=.dockerconfigjson=/tmp/auth-merged.json \
+     --type=kubernetes.io/dockerconfigjson \
+     -n team-x \
+     --dry-run=client -o yaml | kubectl apply -f -
+   ```
+
+4. Reference the merged Secret on each Pod (or attach it to the namespace's default ServiceAccount so Pods inherit it automatically):
+
+   ```yaml
+   apiVersion: v1
+   kind: Pod
+   metadata:
+     name: multi-registry-app
+   spec:
+     imagePullSecrets:
+       - name: glean-merged-pull
+     containers:
+       - name: app
+         image: registry-a.example.com/foo:1.0
+   ```
+
+   Or:
+
+   ```bash
+   kubectl patch serviceaccount default -n team-x \
+     -p '{"imagePullSecrets":[{"name":"glean-merged-pull"}]}'
+   ```
+
+5. Delete the source temp files (`/tmp/auth-*.json`) — they contain credentials in plain text.
+
+## Diagnostic Steps
+
+If a Pod still reports `ImagePullBackOff` after switching to the merged Secret:
+
+- Confirm the Secret type is exactly `kubernetes.io/dockerconfigjson`:
+
+  ```bash
+  kubectl get secret glean-merged-pull -n team-x -o jsonpath='{.type}'
+  ```
+
+- Decode the live Secret to confirm the registry hostname appears under `.auths`:
+
+  ```bash
+  kubectl get secret glean-merged-pull -n team-x \
+    -o jsonpath='{.data.\.dockerconfigjson}' | base64 -d | jq '.auths | keys'
+  ```
+
+- Check the Pod event stream for the exact registry hostname the kubelet tried (it must match the key in `.auths` byte-for-byte, including port if non-standard):
+
+  ```bash
+  kubectl describe pod multi-registry-app -n team-x | tail -20
+  ```
+
+- If the failing host is missing, repeat the merge with the additional source file.
