Docker is the most useful web development tool you’re not using. This course is your guide for building all kinds of web applications with Docker.

You will be introduced to Docker basics including its architecture, images, and containers. Then you'll run various databases and view them via CLI or Adminer. Next, you will learn how easy it is to use WordPress with Docker. After that is the Node.js app and its live editing and debugging with Chrome's devTools. Finally, you will make your own project to practice your Docker knowledge.

By the end of the course, you will be able to confidently use Docker in any of your further projects.

# Docker images

## Build an image from a Dockerfile

```sh
docker image build -t <image_name> .
```
Assuming a `Dockerfile` is in the current directory:

```sh
docker image build -t myimage .
```
The option `-t` allows you to tag the image. In this case, the image named `myimage` is tagged `latest` as no tag was specified. The tag can be specified as:

```sh
docker image build -t myimage:first .
```

The period at the end of the command is essential. It references the application path. You can also use `-f <file>` if you didn’t name your build file “`Dockerfile`”, e.g., if an alternative file name was used:

```sh
docker image build -f mybuildfile.txt -t myimage .
```


## Tag a built image

```sh
docker tag <image_name> [user/repository:tag]
```

Example: tag the `myimage` image with `first` in the Docker Hub `myrepository` repository and the username is `myname`:

```sh
docker tag myimage myname/myrepository:first
```
> 📌 You do not need to make the Docker Hub explicitly. Running this command will create a repository named `myrepository` itself.

## Push tagged images to Docker Hub

```sh
docker push [user/repository]
```

Example:
```sh
docker push  myname/myrepository
```
You can also push with tag:
```sh
docker push  myname/myrepository:first
```

## List Docker images

```sh
docker image ls
docker images
```

View all images, both active and dangling:

```sh
docker image ls -a
```
