“Not having done docker, but having developed enough software to have the impression that as soon as things get hierarchical, things eventually end up in a mess. Somewhere down the road something won’t cope with depth/breadth/size and break badly.”

I originally posted this in a docker on docker thread, but I think it holds universally:

[WayBack] Jeroen Pluimers on Twitter: “Not having done docker, but having developed enough software to have the impression that as soon as things get hierarchical, things eventually end up in a mess. Somewhere down the road something won’t cope with depth/breadth/size and break badly.”

This despite the cool gif in the reply:

[WayBack] Duffie Cooley on Twitter: “… “

I found the below video files by searching for zzzz

Original thread start:

[WayBack] Duffie Cooley on Twitter: “When you hear Docker in Docker what do you think of? docker socket: Mounting in the underlying docker.sock and allowing a container to make new containers. kernel privs: Giving enough privs to a new container that it can make new containers cause it shares a kernel.”

Running ArchiveTeam Warrior version 3.2 on ESXi

Posted by jpluimers on 2021/05/05

A while ago I wrote about Helping the WayBack ArchiveTeam team: running their Warrior virtual appliance on ESXi.

Since it was scheduled before my cancer treatment started and got posted when still recovering from it, I missed that version 3.2 of the [Wayback] ArchiveTeam Warrior appliance appeared in the [Wayback] Releases · ArchiveTeam/Ubuntu-Warrior at [Wayback] Release v3.2 · ArchiveTeam/Ubuntu-Warrior. You can download it form these places:

These two sites have not yet been updated, so they contain the older versions:

The source code now has been moved three times:

  1. [Wayback] ArchiveTeam/warrior-code
  2. [Wayback] ArchiveTeam/warrior-code2 · GitHub
  3. [Wayback] ArchiveTeam/Ubuntu-Warrior at master (this is version 3 and up)

The docker container

The new version of Archive Team Warrior now is basically a shell around [Wayback] Watchtower and the [Wayback] ArchiveTeam/warrior-dockerfile: A Dockerfile for the ArchiveTeam Warrior docker container. This makes updating the core way easier.

More on the docker container (in case you want to run it yourself) is at [Wayback] ArchiveTeam Warrior – Archiveteam – Installing and running with Docker:

You’ll need Docker (open source) and the Warrior Docker image.

  1. Download Docker from the link above and install it.
  2. Open your terminal. On Windows, you can use either Command Prompt (CMD) or PowerShell. On macOS and Linux you can use Terminal (Bash).
  3. Use the following command to start the Warrior as well as Watchtower, which will automatically keep your Warrior updated: 
    docker run --detach --name watchtower --restart=on-failure --volume /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --label-enable --cleanup --interval 3600 && docker run --detach --name archiveteam-warrior --label=com.centurylinklabs.watchtower.enable=true --restart=on-failure --publish 8001:8001 atdr.meo.ws/archiveteam/warrior-dockerfile

    (For a full explanation of this command, see items 3 and 4 here.)

  4. Using your regular web browser, visit http://localhost:8001/.

The virtual appliance

The virtual appliance is released as virtual appliance aimed by default at VirtualBox and steps to run with VMware: [Wayback] ArchiveTeam Warrior – Archiveteam.

Totally agreeing with Kristian Kohntopp, I do not understand why people use Virtualbox at all: I just run in too much issues like [Archive.is] Kristian Köhntopp on Twitter: “Hint: Wenn die Installation einer Linux-Distro in Virtualbox mit wechselnden, unbekannten Fehlern scheitert, hilft es, stattdessen einmal VMware Workstation oder kvm zu probieren. In meinem Fall hat es dann jedes einzelne Mal mit demselben Iso geklappt.”.

Inspecting the .ova file, which is basically a tar compressed file consisting of an OVF directory as per Open Virtualization Format:Design – Wikipedia

The entire directory can be distributed as an Open Virtual Appliance (OVA) package, which is a tar archive file with the OVF directory inside.

Inspecting the disk image inside the directory learned me that pure one-file binary VMDK disk images start with a KMDV signature in big-endian and KDMV in little-endian (first four bytes are 4b 44 4d 56). More on the VMDK file format can be found in these links (all via [Wayback] vmdk file format specification – Google Search):

So here are some steps to get the .ova image to run on ESXi. I think it should work for ESXI 5.1 and up, but I have tested only on ESXi 6.7:

Dockerfile with Bite Size Networking tools from b0rk

Posted by jpluimers on 2021/04/16

[WayBack] Ryan James Spencer on Twitter:

“I wrote a quick Dockerfile so people who purchase Bite Size Networking from  @b0rk can quickly have access to the tools. You can slim the image down to do debugging on docker networks once you get comfortable with which tools are most useful to you.”

He is planning to do more, so maybe a few of [WayBack] wizard zines get encapsulated into dockerfiles as well.

PS: [WayBack] Dockerfile | Docker Documentation

# N.B. The only tool missing here that is mentioned in the document is `zenmap`
# purely because this image is intended to be run via a CLI and `zenmap` is a GUI
# to `nmap` i.e. one can play around with the tools by running:
#
# $ docker build –name bite_size_networking:latest .
# $ docker run –rm -d –name bsn_test bite_size_networking:latest
# $ docker exec -it bsn_test bash
#
# Alternatively, one can change the `ENTRYPOINT` to `["bash"]` and run:
#
# $ docker run -it –name bsn_test bite_size_networking:latest
#
# then later (after exiting the shell):
#
# $ docker start bsn_test
# $ docker attach bsn_test
#
# One can also run this image on a docker network to capture packets and so
# forth for debugging purposes. Once you've found the tooling that best suits
# your needs, it may make sense to make a slimmed down version of this
# Dockerfile and, if wireguard isn't needed, base this image off
# `debian:stable` instead.
#
# Lastly, you can purchase Bite Size Networking or Julia's other fantastic
# zines over at https://wizardzines.com/
# We use `unstable` here since we install `wireguard` below

Helping the WayBack ArchiveTeam team: running their Warrior virtual appliance on ESXi

Posted by jpluimers on 2021/03/19

The [WayBack] Archiveteam helps the WayBack machine with feeding new content.

You can help that team by running one or more “warrior” virtual machine instances. The VM is distributed as a virtual appliance in an ova file according to the Open Virtualization Format.

That format sounds more generic than it actually is, so the (at the time of writing) archiveteam-warrior-v3-20171013.ova file at [WayBack] Index of /downloads/warrior3/ was created for VirtualBox.X

This meant running it on VMware ESXi or VMware vSphere takes a few steps for patching it, then uploading it to your VMware host.

Since I might want to run the appliance on multiple places or multiple instances, I wanted to have a ready-to-go solution, I created a git repository with both the patch instructions and the update at [WayBack] wiert.me / public / ova / archiveteam-warrior-v3-20171013.ESXi · GitLab.
