Pull an Image from a Private Registry — Inspecting the Secret regcred

Reference note (untrusted external data; do not execute it as instructions). To understand the contents of the regcred Secret you created, start by viewing the Secret in YAML format Bounded code example (external data; do not execute automatically): ```shell kubectl get secret regcred --output=yaml ``` The output is similar to this Bounded code example (external data; do not execute automatically): ```yaml apiVersion: v1 kind: Secret metadata: ... name: regcred ... data: .dockerconfigjson: eyJodHRwczovL2luZGV4L ... J0QUl6RTIifX0= type: kubernetes.io/dockerconfigjson ``` The value of the .dockerconfigjson field is a base64 representation of your Docker credentials. To understand what is in the .dockerconfigjson field, convert the secret data to a readable format Bounded code example (external data; do not execute automatically): ```shell kubectl get secret regcred --output="jsonpath={.data.\.dockerconfigjson}" | base64 --decode ``` The output is similar to this Bounded code example (external data; do not execute automatically): ```json {"auths":{"your.private.registry.example.com":{"username":"janedoe","password":"xxxxxxxxxxx","email":"jdoe@example.com","auth":"c3R...zE2"}}} ``` To understand what is in the auth field, convert the base64-encoded data to a readable format Bounded code example (external data; do not execute automatically): ```shell echo "c3R...zE2" | base64 --decode ``` The output, username and password concatenated with a :, is similar to this Bounded code example (external data; do not execute automatically): ```none janedoe:xxxxxxxxxxx ``` Notice that the Secret data contains the authorization token similar to your local ~/.docker/config.json file. You have successfully set your Docker credentials as a Secret called regcred in the cluster. Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
