+# gnunet-docker
+A Dockerfile (and maybe later docker-compose.yml) for getting a running GNUnet docker container.
+
+> This README and parts of the Dockerfile were adapted from https://github.com/compiaffe/gnunet-docker
+
+
+## Build it
+This will take quite a while and will consume a bit of data.
+
+First you need to go to the root of this repo.
+
+```bash
+cd ..
+```
+
+Now you can build the image.
+
+```bash
+docker build -t gnunet .
+```
+
+## Start it from the newly created gnunet image
+Start a container from `gnunet` image, which can access /dev/net/tun, has access to the host network. We are going to name it `gnunet1`.
+
+Note the `--rm` that will delete the container as soon as you stop it and `-ti` gives you an interactive terminal.
+
+#### Linux Users
+```bash
+docker run \
+  --rm \
+  -ti \
+  --privileged \
+  --name gnunet1 \
+  --net=host \
+  -v /dev/net/tun:/dev/net/tun \
+  gnunet
+```
+
+#### Mac Users
+```bash
+docker run \
+  --rm \
+  -it \
+  --privileged \
+  --name gnunet1 \
+  -e LOCAL_PORT_RANGE='40001 40200' \
+  -e GNUNET_PORT=2086 \
+  -p 2086:2086 \
+  -p 2086:2086/udp \
+  -p40001-40200:40001-40200 \
+  -p40001-40200:40001-40200/udp \
+  gnunet
+```
+
+This terminal will keep on printing to screen at the moment. So go on in a new terminal please.
+
+Don't worry about warnings too much...
+
+## Check if you are connected
+Open a new terminal and connect to the container we just started:
+
+```bash
+docker exec -it gnunet1 gnunet-peerinfo -i
+```
+
+If you get a list of peers, all is good.
+
+## Multiple containers on the same host
+### Running
+#### Run Container 1
+```bash
+export GPORT=2086 LPORT='40001-40200' GNAME=gnunet1
+docker run \
+  --rm \
+  -it \
+  --privileged \
+  -e GNUNET_PORT=$GPORT \
+  -e LOCAL_PORT_RANGE="${LPORT/-/ }" \
+  -p $GPORT:$GPORT \
+  -p $GPORT:$GPORT/udp \
+  -p$LPORT:$LPORT \
+  -p$LPORT:$LPORT/udp \
+  --name $GNAME \
+  gnunet
+```
+
+#### Run Container 2
+```bash
+export GPORT=2087 LPORT='40201-40400' GNAME=gnunet2
+docker run \
+  --rm \
+  -it \
+  --privileged \
+  -e GNUNET_PORT=$GPORT \
+  -e LOCAL_PORT_RANGE="${LPORT/-/ }" \
+  -p $GPORT:$GPORT \
+  -p $GPORT:$GPORT/udp \
+  -p$LPORT:$LPORT \
+  -p$LPORT:$LPORT/udp \
+  --name $GNAME \
+  gnunet
+```
+
+### Testing cadet example
+#### Container 1
+```bash
+$ docker exec -it gnunet1 bash
+$ gnunet-peerinfo -s
+I am peer `VWPN1NZA6YMM866EJ5J2NY47XG692MQ6H6WASVECF0M18A9SCMZ0'.
+$ gnunet-cadet -o asdasd
+```
+
+#### Container 2
+```bash
+$ docker exec -it gnunet2 bash
+$ gnunet-cadet VWPN1NZA6YMM866EJ5J2NY47XG692MQ6H6WASVECF0M18A9SCMZ0 asdasd
+```
+
+### Testing file sharing example
+#### Container 1
+```bash
+$ docker exec -it gnunet1 bash
+$ echo 'test' > test.txt
+$ gnunet-publish test.txt
+Publishing `/test.txt' done.
+URI is `gnunet://fs/chk/1RZ7A8TAQHMF8DWAGTSZ9CSA365T60C4BC6DDS810VM78D2Q0366CRX8DGFA29EWBT9BW5Y9HYD0Z1EAKNFNJQDJ04QQSGTQ352W28R.7MYB03GYXT17Z93ZRZRVV64AH9KPWFSVDEZGVE84YHD63XZFJ36B86M48KHTZVF87SZ05HBVB44PCXE8CVWAH72VN1SKYPRK1QN2C98.5'.
+```
+
+#### Container 2
+```bash
+$ docker exec -it gnunet2 bash
+$ gnunet-download -o out.file "gnunet://fs/chk/1RZ7A8TAQHMF8DWAGTSZ9CSA365T60C4BC6DDS810VM78D2Q0366CRX8DGFA29EWBT9BW5Y9HYD0Z1EAKNFNJQDJ04QQSGTQ352W28R.7MYB03GYXT17Z93ZRZRVV64AH9KPWFSVDEZGVE84YHD63XZFJ36B86M48KHTZVF87SZ05HBVB44PCXE8CVWAH72VN1SKYPRK1QN2C98.5"
+100% [============================================================]
+Downloading `out.file' done (0 b/s).
+$ cat out.file
+test
