Oscam is an Open Source Conditional Access Module software used for descrambling DVB transmissions using smart cards. It's both a server and a client.

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 and our announcement here.

Simply pulling 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:









Application Setup

To set up oscam there are numerous guides on the internet. There are too many scenarios to make a quick guide. The web interface is at port 8888.


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

Compatible with docker-compose v2 schemas.

version: "2.1"
container_name: oscam
- PUID=1000
- PGID=1000
- TZ=Europe/London
- <path to data>:/config
- 8888:8888
- /dev/ttyUSB0:/dev/ttyUSB0
restart: unless-stopped

docker cli

docker run -d \
--name=oscam \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-p 8888:8888 \
-v <path to data>:/config \
--device /dev/ttyUSB0:/dev/ttyUSB0 \
--restart unless-stopped \

Passing through Smart Card Readers

If you want to pass through a smart card reader, you need to specify the reader with the --device= tag. The method used depends on how the reader is recognized. The first is /dev/ttyUSBX. To find the correct device, connect the reader and run dmesg | tail on the host. In the output you will find /dev/ttyUSBX, where X is the number of the device. If this is the first reader you connect to your host, it will be /dev/ttyUSB0. If you add one more it will be /dev/ttyUSB1.

If there are no /dev/ttyUSBX device in dmesg | tail, you have to use the USB bus path. It will look similar to the below.


The important parts are the two numbers in the end. The first one is the Bus number, the second is the Device number. To find the Bus and Device number you have to run lsusb on the host, then find your USB device in the list and note the Bus and Device numbers.

Here is an example of how to find the Bus and Device. The output of the lsusb command is below.

Bus 002 Device 005: ID 076b:6622 OmniKey AG CardMan 6121

The first number, the Bus, is 002. The second number, the Device, is 005. This will look like below in the --device= tag.


If you have multiple smart card readers, you add one --device= tag for each reader.


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)





Environment Variables (-e)




for UserID - see below for explanation


for GroupID - see below for explanation


Specify a timezone to use EG Europe/London.

Volume Mappings (-v)




Where oscam should store config files and logs.

Device Mappings (--device)




For passing through smart card readers.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

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)

Docker Mods

Docker Mods Docker Universal Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

  • Shell access whilst the container is running:

    • docker exec -it oscam /bin/bash
