Presumably this also works for MacOS and windows.
While doing this, move away from xdg and home and use this
directories-next crate instead. Reverse connections still seem to
work.
Tui is no longer supported, ratatui is the new hotness. Fortunately
there is very little difference between the two, except I've noticed a
fun new bug in the help screen. (Maybe it's been there the whole time?)
This is the most basic kind of docker querying you will find. Does not
support HTTPS. Seems to work for local docker engines. Has not been
tested against remote docker engines, or full URLs.
Note that if you want this to work you'll have to configure docker to
allow manipulation without being root, i.e., the user you connect as
will need to be in the `docker` group.
This was done instead of pulling in the `bollard` crate. Maybe I'm
being silly, but `bollard` uses a whole lot of other crates in the
name of being general and robust. These crates, however, add an
unacceptable size to the final binary. (In the experiment I ran, on a
release build, the binary size went from 2904696 to 4840968 bytes: an
increase of 1.8 MB. With this patch the release binary is 2986360
bytes, which is an increase of 80k.)
I wanted to see exactly what I could get away with when it came to
talking to docker. This here actually seems like a fine compromise:
HTTP is very simple if you only have to worry about one specific
server, and JSON is not very hard to parse if you don't care too much
about error handling, or are willing to play fast and loose with
punctuation (which I am).
