[Openvpn-as](https://openvpn.net/index.php/access-server/overview.html) is a full featured secure network tunneling VPN software solution that integrates OpenVPN server capabilities, enterprise management capabilities, simplified OpenVPN Connect UI, and OpenVPN Client software packages that accommodate Windows, MAC, Linux, Android, and iOS environments. OpenVPN Access Server supports a wide range of configurations, including secure and granular remote access to internal network and/ or private cloud network resources and applications with fine-grained access control.

## Supported Architectures

Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/). 

Simply pulling `linuxserver/openvpn-as` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

| Architecture | Tag |
| :----: | --- |
| x86-64 | latest |


## Usage

Here are some example snippets to help you get started creating a container from this image.

### docker

```
docker create \
  --name=openvpn-as \
  --cap-add=NET_ADMIN \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e INTERFACE=eth0 `#optional` \
  -p 943:943 \
  -p 9443:9443 \
  -p 1194:1194/udp \
  -v <path to data>:/config \
  --restart unless-stopped \
  linuxserver/openvpn-as
```


### docker-compose

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2"
services:
  openvpn-as:
    image: linuxserver/openvpn-as
    container_name: openvpn-as
    cap_add:
      - NET_ADMIN
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - INTERFACE=eth0 #optional
    volumes:
      - <path to data>:/config
    ports:
      - 943:943
      - 9443:9443
      - 1194:1194/udp
    restart: unless-stopped
```

## Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.

### Ports (`-p`)

| Parameter | Function |
| :----: | --- |
| `943` | Admin GUI port. |
| `9443` | TCP port. |
| `1194/udp` | UDP port. |


### Environment Variables (`-e`)

| Env | Function |
| :----: | --- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `TZ=Europe/London` | Specify a timezone to use EG Europe/London. |
| `INTERFACE=eth0` | With bridge networking, leave it as eth0 (or don't include at all), if host or macvlan, set it to your host's network interface, found by running `ifconfig` |

### Volume Mappings (`-v`)

| Volume | Function |
| :----: | --- |
| `/config` | Where openvpn-as should store configuration files. |



## User / Group Identifiers

When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:

```
  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
```

## Application Setup

The admin interface is available at `https://<ip>:943/admin` with a default user/password of admin/password

During first login, make sure that the "Authentication" in the webui is set to "Local" instead of "PAM". Then set up the user accounts with their passwords (user accounts created under PAM do not survive container update or recreation).

The "admin" account is a system (PAM) account and after container update or recreation, its password reverts back to the default. It is highly recommended to block this user's access for security reasons:
1) Create another user and set as an admin,
2) Log in as the new user,
3) Delete the "admin" user in the gui,
4) Modify the `as.conf` file under config/etc and replace the line `boot_pam_users.0=admin` with `#boot_pam_users.0=admin` (this only has to be done once and will survive container recreation)



## Support Info

* Shell access whilst the container is running: 
  * `docker exec -it openvpn-as /bin/bash`
* To monitor the logs of the container in realtime: 
  * `docker logs -f openvpn-as`
* Container version number 
  * `docker inspect -f '{{ index .Config.Labels "build_version" }}' openvpn-as`
* Image version number
  * `docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/openvpn-as`
