What are some examples of using Docker secrets?
Docker secrets are used to manage sensitive data, like passwords and API keys, securely. For example, you can store a database password as a secret and then reference it in your Docker Compose file.
Can you show me how to create a Docker secret?
Sure! You can create a Docker secret using the command: echo 'my_secret_password' | docker secret create my_db_password -
. This will create a secret named my_db_password
.
How do I use this secret in a Docker service?
To use the secret in a Docker service, you can define it in your Docker Compose file like this: secrets: my_db_password
. Then, you can access it in your container at /run/secrets/my_db_password
.
Are there any best practices for managing Docker secrets?
