This is going to be a small post since it has to deal with kubernetes and secrets. Yet it is a very useful once since adding secrets is so common yet so easy to forget (guilty as charged).<\/p>\n

So we will cover username and password, key\/values, file uploading, secrets.<\/p>\n

Upload username and password using command line.<\/p>\n

kubectl create secret generic accountpassword --from-literal=username=yourusername --from-literal=password=yourpassword<\/pre>\n
Upload just a key<\/p>\n
kubectl create secret generic application-key --from-literal=key=yourusername<\/pre>\n
Upload username and password through files<\/p>\n
printf \"yourusername\" > username.txt\nprintf \"yourpassword\" > password.txt\nkubectl create secret generic accountpassword --from-file=.\/username.txt --from-file=.\/password.txt<\/pre>\n
Then let\u2019s upload a secret. Be aware that this secret can be used with your secret rules.<\/p>\n
kubectl create secret tls your-server-tls --key .\/privkey.pem --cert .\/fullchain.pem<\/pre>\n
Another step is to upload a file. This file can then be used by being mounted on your container.<\/p>\n
kubectl create secret generic secretfile --from-file=key.json=.\/secret_json.yaml<\/pre>\n
Then you can mount it to the pod<\/p>\n
spec:\n      volumes:\n      - name: secret-json\n        secret:\n          secretName: secretfile\n      containers:\n      - name: containername\n        volumeMounts:\n        - name: secret-json\n          mountPath: \/var\/secrets\/json<\/pre>\n
That\u2019s all! The full docs can be found here<\/a>.<\/p>\n
