A Secret is an object that contains a small amount of sensitive data such as a password, a token, or a key. Such information might otherwise be put in a Pod specification or in an image; putting it in a Secret object allows for more control over how it is used, and reduces the risk of accidental exposure.
Sign in with
project-regular account, enter into one project such as
demo-project created in Getting Start with Multi-Tenant Management, then select Configuration Center → Secrets.
1.1. Click Create Secret button, then fill in basic information in the pop-up window. There are two ways to create a Secret, i.e., UI Mode and Edit Mode. The following mainly introduces each step of UI mode. If you prefer edit mode, you can click on the Edit Mode button, which supports yaml format and json format. Edit mode makes it easy for users who are used to editing yaml-like file directly.
1.2. On the basic information page, enter the name of the Secret. You can also fill in the description as necessary.
Click Next when you're done.
In the Secret settings, there are four types of secret as below are supported:
Data: Password: hello123 Username: guest
apiVersion: v1 Data: Tls.crt: base64 encoded cert Tls.key: base64 encoded key Kind: Secret Metadata: Name: testsecret Namespace: default Type: kubernetes.io/tls
Image Repository Secret (kubernetes.io/dockerconfigjson): It is used to store the authentication information of an image registry, such as the following information, see Image Registry:
Custom: Allows users to create a type (type) that is similar to the default (Opaque) type. Both of them are key-value pairs.
Secrets can be mounted as data volumes or exposed as environment variables to be used by a container in a Pod.
For more information on how to use the Secret, see Quick-Start - Deploy a MySQL Application.
Enter into Configuration Center→ Secrets, click Create.
Enter its name, e.g.
dockerhub-id, then choose Next.
Select Image Repository Secret from the dropdown list, enter
docker.io into Registry Address, then input your DockerHub user name and password. Click Create when you are done.
Creating a GitHub secret is similiar as above. Enter its name, e.g.
