# Commands
## List all the images
```bash
docker images
```
## Download image
```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
# docker start [container_id]
docker start a6e16354239fc76b4cc89216bfe46f0260500a7e798d62e319af213345bb13c8
### 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:
> 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
```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
```
```
