# Commands

## List all the images

```bash
docker images
```

## Download image

[https://hub.docker.com/](https://hub.docker.com/)

```bash
# docker pull [image]
docker pull mysql
```

## Delete image

```bash
# docker image rm [image]
# docker image rm [image]:[tag]
docker image rm mysql
docker image rm mysql:latest
docker image rm mysql:16
```

## Create a container with the image

### With random container name

It will generate an ID to the container.

```bash
# docker container create [image]
# docker create [image]
docker create mysql
```

Id generated:

```
a6e16354239fc76b4cc89216bfe46f0260500a7e798d62e319af213345bb13c8
```

### With custom container name

```bash
docker create --name monguito mongo
```

Id generated:

```
e1d70ca8719dcf07987eae76bac9a621d4531e9c9b8bdf8328b647e649d3f438
```

## Start a container

### Using the ID of the container

<pre class="language-bash"><code class="lang-bash"><strong># docker start [container_id]
</strong><strong>docker start a6e16354239fc76b4cc89216bfe46f0260500a7e798d62e319af213345bb13c8
</strong></code></pre>

### Using the custom name of the container

```bash
docker start monguito
docker ps # we will see the container running
```

### Using environment variables

For example, to create a mongodb container with specific user and password, to then use an app to connect to it, we use the env variable described in mongodb hub:

[https://hub.docker.com/\_/mongo](https://hub.docker.com/_/mongo)

> Each image has different ways to configure

```bash
docker create -p27017:27017 --name monguito -e MONGO_INITDB_ROOT_USERNAME=nico -e MONGO_INITDB_ROOT_PASSWORD=password mongo
```

## Status of containers running&#x20;

```bash
docker ps
```

```bash
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS       NAMES
a6e16354239f   mysql     "docker-entrypoint.s…"   4 minutes ago   Up 2 seconds   27017/tcp   pedantic_rubin
```

## Stop a container

```bash
docker stop a6e16354239f
docker ps
# There is no one container running
```

## List of containers started and off

List all the containers in system.

```bash
docker ps --all
docker ps -a
```

```bash
CONTAINER ID   IMAGE     COMMAND                  CREATED        STATUS                    PORTS     NAMES
a6e16354239f   mysql     "docker-entrypoint.s…"   22 hours ago   Exited (0) 22 hours ago             pedantic_rubin
```

## Delete a container

#### Using name

```bash
docker rm pedantic_rubin
docker ps -a #container deleted
```

## Expose a container in a host port

### Custom port

```bash
# docker create -p[port_in_host]:[port_in_container] --name [name] [image]
docker create -p27017:27017 --name monguito mongo
```

```bash
docker start monguito
docker ps
```

```bash
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                                           NAMES
6c97203a3708   mongo     "docker-entrypoint.s…"   2 minutes ago   Up 2 seconds   0.0.0.0:27017->27017/tcp, :::27017->27017/tcp   monguito
```

### Random port

```bash
# docker create -p[port_in_container] --name [name] [image]
docker create -p27017 --name manguito mongo
```

```bash
docker start manguito
docker ps
```

```bash
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS         PORTS                                           NAMES
2bdec62e384c   mongo     "docker-entrypoint.s…"   6 seconds ago   Up 1 second    0.0.0.0:32768->27017/tcp, :::32768->27017/tcp   manguito
```

## Check logs of container

```bash
docker logs monguito
```

Or to stay watching those logs:

```bash
docker logs --follow monguito
```

## Download the image, create and start the container

### With logs view, random data

```bash
docker run mongo
```

### Without logs view, detach mode and random data

```bash
docker run -d mongo
```
