How can I log in to the docker container securely?
I am a DevOps engineer and I am assigned to manage a dockerized microservices architecture in my company. Provide me the steps by which I can securely log in to the docker container registry within a CI/CD pipeline.
There are various methods present by which you can get through easily and safely login to the docker container. Here is one of the examples given using environment variables and the docker CLI:-
Step 1:- Set Environment Variables by using
Export DOCKER_ REGISTRY_ USER = “ your_username”
Export DOCKER_ REGISTRY_ PASSWORD= “ your_ password”
Step 2:- Use Docker CLI in CI/CD script by using
#log in to the docker registry
Docker login -u $DOCKER_ REGISTRY_ USER -p $DOCKER_ REGISTRY_ PASSWORD your.registr.url
You can replace your. register. URL with the real URL of your docker registry.
Here is the combined example given of the above scenario by using the Docker CLI and environment variables:-
# Using environment variables for credentials (example)
Export DOCKER_REGISTRY_USER=”your_username”
Export DOCKER_REGISTRY_PASSWORD=”your_password”
# Login to the Docker registry within your CI/CD script
Docker login -u $DOCKER_REGISTRY_USER -p $DOCKER_REGISTRY_PASSWORD your.registry.url
