## 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 node:lts-alpine as builder
RUN mkdir -p /verdaccio/plugins \
  && cd /verdaccio/plugins \
  && npm install --global-style --no-bin-links --omit=optional verdaccio-auth-memory@latest
FROM verdaccio/verdaccio:5
ADD docker.yaml /verdaccio/conf/config.yaml
COPY --chown=$VERDACCIO_USER_UID:root --from=builder \
  /verdaccio/plugins/node_modules/verdaccio-auth-memory \
  /verdaccio/plugins/verdaccio-auth-memory
```

For more information check real plugin examples with Docker in our [source code](https://github.com/verdaccio/verdaccio/tree/master/docker-examples/v5/plugins).

### 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:
