# How to use Docker containers on the whonix workstation
|
||||
|
||||
|
||||
## How to install Docker
|
||||
|
||||
As usual we install docker via apt like so:
|
||||
```sh
|
||||
[workstation user ~]% sudo apt install docker.io docker-compose -y
|
||||
```
|
||||
|
||||
## How to make sure that Docker pulls images through Tor
|
||||
|
||||
```sh
|
||||
[workstation user ~]% sudo docker pull alpine
|
||||
Using default tag: latest
|
||||
Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 10.152.152.10:53: read udp 10.152.152.11:33883->10.152.152.10:53: i/o timeout
|
||||
zsh: exit 1 sudo docker pull alpine
|
||||
```
|
||||
Here as you can see when we try to pull an alpine image, docker can't pull it, to fix that we need to make sure that docker pulls through the localhost tor socks5 proxy on port 9050:
|
||||
|
||||
```sh
|
||||
[workstation user ~]% sudo mkdir /etc/systemd/system/docker.service.d/
|
||||
[workstation user ~]% sudo vim /etc/systemd/system/docker.service.d/proxy.conf
|
||||
[workstation user ~]% cat /etc/systemd/system/docker.service.d/proxy.conf
|
||||
[Service]
|
||||
Environment="HTTP_PROXY=socks5://127.0.0.1:9050"
|
||||
Environment="HTTPS_PROXY=socks5://127.0.0.1:9050"
|
||||
```
|
||||
|
||||
Now that's created, we reload the systemd service and try to pull the alpine docker image again:
|
||||
```sh
|
||||
[workstation user ~]% sudo systemctl daemon-reload
|
||||
[workstation user ~]% sudo systemctl restart docker
|
||||
[workstation user ~]% docker pull alpine
|
||||
Using default tag: latest
|
||||
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/images/create?fromImage=alpine&tag=latest": dial unix /var/run/docker.sock: connect: permission denied
|
||||
zsh: exit 1 docker pull alpine
|
||||
[workstation user ~]% sudo !!
|
||||
[workstation user ~]% sudo docker pull alpine
|
||||
Using default tag: latest
|
||||
latest: Pulling from library/alpine
|
||||
fe07684b16b8: Pull complete
|
||||
Digest: sha256:8a1f59ffb675680d47db6337b49d22281a139e9d709335b492be023728e11715
|
||||
Status: Downloaded newer image for alpine:latest
|
||||
docker.io/library/alpine:latest
|
||||
```
|
||||
|
||||
And that's it! we managed to pull the alpine image as intended.
|
||||
|
||||
## Sidenotes
|
||||
|
||||
1) you can't connect to the internet from a docker container that is in a whonix workstation, and the [whonix developers won't bother providing support for it](https://forums.whonix.org/t/how-can-you-make-a-docker-container-inside-whonix-workstation-connect-to-the-internet/21772/2)
|
||||
2) disabling the whonix firewall does not fix the issue either
|
||||
3) you cant edit the socsk5 port on whonix workstation by editing /etc/tor/torrc to try and set SOCKSPort to 0.0.0.0:9050, which would make it easy to access the tor socks port from the docker container.
|
||||
3) you can make a docker-compose.yml image with the docker container set to network_mode: host to be able to access the 9050 socks5 port on the 10.152.152.11 local IP, but it doesnt seem to be able to resolve domains either for some reason.
|
||||
|
||||
```
|
||||
[workstation user ~]% cat docker-compose.yml
|
||||

|
||||
myalpine:
|
||||

|
||||

4) tested with a forgejo container, with the socks5 proxy set onto 10.152.152.11 on port 9050, it is unable to mirror repositories that are on external clearnet git instances.
|
||||
|
||||
TLDR: if you run a docker container inside of a whonix workstation VM, it will remain truly isolated and unable to communicate with the internet.

And now from there, we should be able to mirror external repositories on gitea by making the traffic go through Tor aswell. As an example, let's create a git mirror of the official [Monero](../monero2024/index.md) repository that currently sits on [Github](https://github.com/monero-project/monero):

|

**SIDENOTE:** [you can't mirror clone repositories that are on other forgejo onion-only instances](https://codeberg.org/forgejo/forgejo/issues/8193) due to an upstream issue in [curl](https://github.com/curl/curl/issues/17363) So in the meantime, you can only use the mirror function to clone other clearnet repositories.
|

|

Now be aware that it's going to take longer than it usually would to get the repository due to the low bandwidth that Tor has, so be be patient and wait until it finishes:
