## Running Verdaccio using Docker {#running-verdaccio-using-docker}

To run the docker container:

```bash
docker run -it --rm --name verdaccio -p 4873:4873 verdaccio/verdaccio
```

The last argument defines which image to use.
The above line will pull the latest prebuilt image from dockerhub, if you haven't done that already.

If you have [build an image locally](#build-your-own-docker-image) use `verdaccio` as the last argument.


You can use `-v` to bind mount `conf`, `storage` and `plugins` to the hosts filesystem (example below).

Note that if you do mount conf like this, that you will first need to supply a copy of config.yaml in that directory; the Docker container will not start properly if this file is missing. You can copy this file initially from https://github.com/verdaccio/verdaccio/blob/5.x/conf/docker.yaml. However, note the security warnings in that file; you will definitely want to lock it down in production.

```bash
V_PATH=/path/for/verdaccio; docker run -it --rm --name verdaccio \
  -p 4873:4873 \
  -v $V_PATH/conf:/verdaccio/conf \
  -v $V_PATH/storage:/verdaccio/storage \
  -v $V_PATH/plugins:/verdaccio/plugins \
  verdaccio/verdaccio
```
> if you are running in a server, you might want to add -d to run it in the background

>Note: Verdaccio runs as a non-root user (uid=10001) inside the container, if you use bind mount to override default, 
you need to make sure the mount directory is assigned to the right user. In above example, you need to run `sudo chown -R 10001:65533 /path/for/verdaccio` otherwise 
you will get permission errors at runtime. 
[Use docker volume](https://docs.docker.com/storage/volumes/) is recommended over using bind mount.

Verdaccio 4 provides a new set of environment variables to modify either permissions, port or http protocol. Here the complete list:

Property | default | Description
--- | --- | ---
VERDACCIO_APPDIR | `/opt/verdaccio` | the docker working directory
VERDACCIO_USER_NAME | `verdaccio` | the system user
VERDACCIO_USER_UID | `10001` | the user id being used to apply folder permissions
VERDACCIO_PORT | `4873` | the verdaccio port
VERDACCIO_PROTOCOL | `http` | the default http protocol



### SELinux {#selinux}

If SELinux is enforced in your system, the directories to be bind-mounted in the container need to be relabeled. Otherwise verdaccio will be forbidden from reading those files.

```
 fatal--- cannot open config file /verdaccio/conf/config.yaml: Error: CONFIG: it does not look like a valid config file
```

If verdaccio can't read files on a bind-mounted directory and you are unsure, please check `/var/log/audit/audit.log` to confirm that it's a SELinux issue. In this example, the error above produced the following AVC denial.

```
type=AVC msg=audit(1606833420.789:9331): avc:  denied  { read } for  pid=1251782 comm="node" name="config.yaml" dev="dm-2" ino=8178250 scontext=system_u:system_r:container_t:s0:c32,c258 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file permissive=0
```

`chcon` can change the labels of shared files and directories. To make a directory accessible to containers, change the directory type to `container_file_t`.

```sh
$ chcon -Rt container_file_t ./conf
```

If you want to make the directory accessible only to a specific container, use `chcat` to specify a matching SELinux category.

An alternative solution is to use [z and Z flags](https://docs.docker.com/storage/bind-mounts/#configure-the-selinux-label). To add the `z` flag to the mountpoint `./conf:/verdaccio/conf` simply change it to `./conf:/verdaccio/conf:z`. The `z` flag relabels the directory and makes it accessible by every container while the `Z` flags relables the directory and makes it accessible only to that specific container. However using these flags is dangerous. A small configuration mistake, like mounting `/home/user` or `/var` can mess up the labels on those directories and make the system unbootable.

### Plugins {#plugins}
Plugins can be installed in a separate directory and mounted using Docker or Kubernetes, however make sure you build plugins with native dependencies using the same base image as the Verdaccio Dockerfile.

```docker
FROM verdaccio/verdaccio

USER root

ENV NODE_ENV=production

RUN npm i && npm install verdaccio-s3-storage

USER verdaccio
```

### Docker and custom port configuration {#docker-and-custom-port-configuration}
Any `host:port` configured in `conf/config.yaml` under `listen` **is currently ignored when using docker**.

If you want to reach Verdaccio docker instance under different port, lets say `5000`
in your `docker run` command add the environment variable `VERDACCIO_PORT=5000` and then expose the port `-p 5000:5000`.

```bash
V_PATH=/path/for/verdaccio; docker run -it --rm --name verdaccio \
  -e "VERDACCIO_PORT=8080" -p 8080:8080 \  
  verdaccio/verdaccio
```

Of course the numbers you give to the `-p` parameter need to match.

### Using HTTPS with Docker {#using-https-with-docker}
You can configure the protocol verdaccio is going to listen on, similarly to the port configuration.
You have to overwrite the default value("http") of the `PROTOCOL` environment variable to "https", after you specified the certificates in the config.yaml.

```bash
docker run -it --rm --name verdaccio \
  --env "VERDACCIO_PROTOCOL=https" -p 4873:4873
  verdaccio/verdaccio
```

### Using docker-compose {#using-docker-compose}

1. Get the latest version of [docker-compose](https://github.com/docker/compose).
2. Build and run the container:

```bash
$ docker-compose up --build
```

You can set the port to use (for both container and host) by prefixing the above command with `VERDACCIO_PORT=5000 `.


```yaml
version: '3.1'

services:
  verdaccio:
    image: verdaccio/verdaccio
    container_name: "verdaccio"
    networks:
      - node-network
    environment:
      - VERDACCIO_PORT=4873
    ports:
      - "4873:4873"
    volumes:
      - "./storage:/verdaccio/storage"
      - "./config:/verdaccio/conf"
      - "./plugins:/verdaccio/plugins"  
networks:
  node-network:
    driver: bridge
```

Docker will generate a named volume in which to store persistent application data. You can use `docker inspect` or `docker volume inspect` to reveal the physical location of the volume and edit the configuration, such as:

```bash
$ docker volume inspect verdaccio_verdaccio
[
    {
        "Name": "verdaccio_verdaccio",
        "Driver": "local",
        "Mountpoint": "/var/lib/docker/volumes/verdaccio_verdaccio/_data",
        "Labels": null,
        "Scope": "local"
    }
]

```

## Build your own Docker image {#build-your-own-docker-image}

```bash
docker build -t verdaccio .
```

There is also an npm script for building the docker image, so you can also do:

```bash
yarn run build:docker
```

Note: The first build takes some minutes to build because it needs to run `npm install`,
and it will take that long again whenever you change any file that is not listed in `.dockerignore`.

Please note that for any of the above docker commands you need to have docker installed on your machine and the docker executable should be available on your `$PATH`.

## Docker Examples {#docker-examples}

There is a separate repository that hosts multiple configurations to compose Docker images with `verdaccio`, for instance, as reverse proxy:
