 # VPP Containerlab Docker image
 
-This docker container creates a VPP instance based on the latest release.  It starts up as per
-normal, using /etc/vpp/startup.conf (which Containerlab will replace), and once started, it'll
-execute /etc/vpp/bootstrap.vpp within the dataplane. There are three relevant files:
+## User Documentation
 
-1.   `manual-pre.vpp` -- can be supplied by the user, to run any configuration statements before
-     containerlab takes control.
+The file `vpp.clab.yml` contains an example topology existing of two VPP instances connected each to
+one Alpine linux container, in the following topology:
 
-1.   `clab.vpp` -- generated by containerlab. Its purpose is to bind the `vethpair` interfaces
-     into theo dataplane (see below).
+![learn-vpp](learn-vpp.png)
 
-1.   `manual-post.vpp` -- can be supplied by the user, to run any configuration statements after
-     containerlab is finished with its per-lab statements.
+This container ships with both Bird2 and FRRouting as controlplane agents.
 
-## Building
+You can deploy:
+*   Bird2: `containerlab deploy --topo vpp-bird.clab.yml`.
+*   FRR: `containerlab deploy --topo vpp-frr.clab.yml`.
+
+three relevant files for VPP are included in this repository:
+1.   `config/vpp*/vppcfg.yaml` configures the dataplane interfaces, including a loopback address.
+1.   `config/vpp*/bird-local.conf` configures the controlplane to enable BFD and OSPF.
+1.   `config/vpp*/frr.conf` configures the controlplane to enable BFD and OSPF.
+
+Once the lab comes up, you can SSH to the VPP containers (`vpp1` and `vpp2`) which will have your
+SSH keys installed (if available). Otherwise, you can log in as user `root` using password `vpp`.
+
+VPP runs its own network namespace called `dataplane`, which is very similar to SR Linux default
+`network-instance`. You can join it to take a look:
 
 ```bash
-docker build -f Dockerfile.bookworm . -t pimvanpelt/vpp-containerlab
+pim@summer:~/src/vpp-containerlab$ ssh root@vpp1
+root@vpp1:~# nsenter --net=/var/run/netns/dataplane

-## Starting the container
+The two clients are running a minimalistic Alpine Linux container, which doesn't ship with SSH by
+default. You can enter the containers as following:
 
+```bash
+pim@summer:~/src/vpp-containerlab$ docker exec -it client1 sh
+/ # ip addr show dev eth1
+531235: eth1@if531234: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 9500 qdisc noqueue state UP

 ```
-docker network create --driver=bridge network2 --subnet=172.19.1.0/24
+
+From the vantage point of `client1`, the first hop represents the `vpp1` node, which forwards to
+`vpp2`, which finally forwards to `client2`.
+
+## Developer Documentation
+
+This docker container creates a VPP instance based on the latest VPP release. It starts up as per
+normal, using /etc/vpp/startup.conf (which Containerlab might replace when it starts its
+containers). Once started, it'll execute `/etc/vpp/bootstrap.vpp` within the dataplane. There are
+two relevant files:
+
+1.   `clab.vpp` -- generated by `files/init-container.sh`. Its purpose is to bind the `veth`
+     interfaces that containerlab has added to the container into the VPP dataplane (see below).
+1.   `vppcfg.vpp` -- generated by `files/init-container.sh`. Its purpose is to read the user
+     specified `vppcfg.yaml` file and convert it into VPP CLI commands. If no YAML file is
+     specified, or if it is not syntactically valid, an empty file is generated instead.
+
+For Containerlab users who wish to have more control over their VPP bootstrap, it's possible to
+bind-mount `/etc/vpp/bootstrap.vpp`.
+
+### Building
+
+```bash
+IMG=git.ipng.ch/ipng/vpp-containerlab
+TAG=latest
+docker build --no-cache --build-arg REPO=release -f docker/Dockerfile -t $IMG docker/
+docker image tag $IMG $IMG:$TAG
+docker push $IMG
+docker push $IMG:$TAG
+```
+
+### Testing standalone container
+
+```bash
+docker network create --driver=bridge clab-network --subnet=192.0.2.0/24 \
+                      --ipv6 --subnet=2001:db8::/64
 docker rm clab-pim

+           --device=/dev/net/tun:/dev/net/tun \
            --device=/dev/vhost-net:/dev/vhost-net \
-           --privileged=True --name clab-pim \
-           docker.io/pimvanpelt/vpp-containerlab
-docker network connect network2 clab-pim
+           --privileged --name clab-pim \
+           git.ipng.ch/ipng/vpp-containerlab:latest
+docker network connect clab-network clab-pim
 ```
 
-## Configuring VPP
+#### A note on DPDK
 
+DPDK will be disabled by default as it requires hugepages and VFIO and/or UIO to use physical
+network cards. If DPDK at some future point is desired, mapping VFIO can be done by adding this:
 ```
+           --device=/dev/vfio/vfio:/dev/vfio/vfio
+```
+
+or in Containerlab, using the `devices` feature:
+
+```yaml
+my-node:
+  image: git.ipng.ch/ipng/vpp-containerlab:latest
+  kind: fdio_vpp
+  devices:
+    - /dev/vfio/vfio
+    - /dev/net/tun
+    - /dev/vhost-net
+```
+
+If using DPDK in a container, one of the userspace IO kernel drivers must be loaded in the host
+kernel. Options are `igb_uio`, `vfio_pci`, or `uio_pci_generic`:
+
+```bash
+$ sudo modprobe igb_uio
+$ sudo modprobe vfio_pci
+$ sudo modprobe uio_pci_generic
+```
+
+Particularly the VFIO driver needs to be present before one can attempt to bindmount
+`/dev/vfio/vfio` into the container!
+
+### Configuring VPP
+
+When Containerlab starts the docker containers, it'll offer one or more `veth` point to point
+network links, which will show up as `eth1` and further. `eth0` is the default NIC that belongs to
+the management plane in Containerlab (the one which you'll see with `containerlab inspect`). Before
+VPP can use these `veth` interfaces, it needs to bind them, like so:
+
+```bash
 docker exec -it clab-pim vppctl
 ```
 
 and then within the VPP control shell:
 
 ```
-vpp-clab# create host-interface v2 name eth1
-vpp-clab# set interface name host-eth1 eth1
-vpp-clab# set interface mtu 1500 eth1
-vpp-clab# set interface ip address eth1 172.19.1.2/24
-vpp-clab# set interface ip address eth1 fec0::2/64
-vpp-clab# set interface state eth1 up
+create host-interface v2 name eth1
+set interface name host-eth1 eth1
+set interface mtu 1500 eth1
+set interface ip address eth1 192.0.2.2/24
+set interface ip address eth1 2001:db8::2/64
+set interface state eth1 up
 ```
+
+Containerlab will attach these `veth` pairs to the container, and replace our Docker CMD with one
+that waits for all of these interfaces to be added (typically called `if-wait.sh`). In our own CMD,
+we then generate a config file called `/etc/vpp/clab.vpp` which contains the necessary VPP commands
+to take control over these `veth` pairs.
