-You may need to add those host keys to your known hosts file.
-Either connect interactively, or (for scripts):
-
-```sh
-hosts="$(docker network inspect bridge  | jq -r '.[].Containers | .[] | .Name + " " + .IPv4Address' | \
-    cut -d/ -f1)"

-done
-```
-
-Check if they ping:
-
-```sh
-ansible -i $docker_hosts all -m ping
-```

-If you have a python script which requires a packages - e.g. `graphviz` - you can automate the setup with a `Makefile`.
-The `Makefile` will:

-2. Use one of the installer script to install local packages.
-3. Install a symbolic link to python.

-# Context
-
-Python coders don't like updating their projects, they just expect everyone to install the same version of everything that they have.
-Historically, people dealt with this by installing only half a dozen copies of `graphviz`; but now each python project uses a local environment, with a local copy of `graphviz`, which means everyone gets to install a new copy of `graphviz` every time they try out a project.
-
-Downloading 40MB of software for each 40-line script you write is called 'virtual environments' because it sounds cool.
-We can make it even cooler with `make`, but not yet, because python - like the fae of old - will not fetch anything until you know its true name.

-```sh
-command -v python
-realpath `!!`
-```
-
-You must reveal that true path, because `python` is always a relative symbolic link, to an absolute symbolic link, which leads to a shortcut.
-We can finally let `make` know how to invoke python, and where it will install `graphviz`.
-
-If your python's version is '3.14', then python needs its packages placed in `${somewhere}/lib/python3.14/site-packages/`.
-You must create a new, local, name for these packages, because - like the fey of old - python demands a private name in return for revealing its true name.
-
-I'll call mine `camelot`, because the path is long and arduous.
-Set up the Makefiles like this:
-
-```make
-py_link != command -v python
-py != realpath $(py_link)
-version != basename $(py)
-
-virtenv = camelot
-```
-
-Now you can ask for a local `pip` script, which can install the python packages:
-
-```make
-    [...]
-
-$(virtenv)/bin/pip:
-    $(py) -m venv $(virtenv)
-```
-
-Finally, list the packages you want in `requirements.txt`, and make `pip` install from it.
-
-
-```sh
-ppkg=graphviz
-echo ${ppkg} > requirements.txt
-```
-
-```make
-    [...]
-
-pkgs = $(virtenv)/lib/$(version)/site-packages/
-
-$(pkgs): $(virtenv)/bin/pip
-$(pkgs): requirements.txt
-    $(virtenv)/bin/pip install -r $<
-```
-
-The complete Makefile looks like this:
-
-
-```make
-all: .default
-
-py_link != command -v python
-py != realpath $(py_link)
-version != basename $(py)
-
-virtenv = camelot
-
-$(virtenv)/bin/pip:
-    $(py) -m venv $(virtenv)
-
-pkgs = $(virtenv)/lib/$(version)/site-packages/
-
-$(pkgs): $(virtenv)/bin/pip
-$(pkgs): requirements.txt
-    $(virtenv)/bin/pip install -r $<
-
-.PHONY: .default
-.default: $(pkgs)

-1. Install `vi`.

-The [ancient wisdom](https://stackoverflow.com/questions/1218390/what-is-your-most-productive-shortcut-with-vim/1220118#1220118) is correct - everyone should start with `vi`.
-But the standard wisdom fails to mention writing.
-So people just 'try to remember', then they edit a couple of configuration files with `vim`, then stop, because it's a pain to think about keystrokes while thinking about how the configuration file works.
-Nobody can learn like that.
-
-Learn with a blog, or writing emails in `vim`, or writing anything, as long as it's *real writing*.
-Write a journal or some recipes.
-Write literally anything which is written in paragraphs.
-
-And while you're writing, remember one rule: if you want something, `vi` can do it, you just need to look up how.
-
-Blog first, then try out some of these commands:
