How to use Docker?

Create Dockerfile

The file name can also be named differently, such as 1.Dockerfile. Use the -f parameter to specify the Dockerfile name when using docker build.

Build Image

-t represents the image name

# directly tag
docker build . -t ai-assistant:0.0.1

# Select the specified Dockerfile to build an image.
docker build . -f Dockerfile -t cwy829/ai-assistant:0.0.1

Start Container

-d represents starting the container in the background. -p represents specifying the port mapping, where the former is the host port and the latter is the container port. -v represents volume mapping. Since this project requires a configuration file, a configuration file needs to be created on the host to map to the container, otherwise, container startup cannot request normally. --name represents the name of the container instance to be started. ai-assistant:0.6.0 is the image name.

docker run -d -p 3000:3000 -v ~/docker-data/.env:/ai-assistant/.env --name ai-assistant ai-assistant:0.0.1

Publish Image

Login

Firstly, visit dockerhub and create an account.

After logging in, enter docker login in the local docker client or command line tool for client login. This step requires a global proxy. Otherwise, login will fail.

Next, label the username and version of the local image.

docker image tag [imageName] [username]/[repository]:[tag]

# Example
docker image tag ai-assistant:0.0.1 cwy829/ai-assistant:0.0.1

Finally, publish the image file.

docker image push [username]/[repository]:[tag]

# Example
docker image push cwy829/ai-assistant:0.0.1

Once published successfully, the published image can be seen on hub.docker.com.
