+# podman
+- a [[tool]].
+	- [[docker]] alternative.
+		- advantages: supposedly more secure (doesn't require root), less complex architecture.
+		- part of the [[fedora]] project.
+	- https://social.coop/web/statuses/105866648612458840
+	- [[install]] https://podman.io/getting-started/installation
+	- #go https://podman.io/
+	- #git https://github.com/containers/podman
+	- [[rootless shortcomings]] https://github.com/containers/podman
+		- there are enough that I'll probably go with a root-based setup to begin with, while learning the system.
+		- else when things fail I'll probably find it hard to figure out if it's due to rootless or something else.
+- [[notes on adoption]]
+	- On Debian 11, I had to install package [[uidmap]] to avoid https://github.com/containers/podman/issues/9271
+	- Also I had to edit /etc/containers/registries.conf and set:
+		- `unqualified-search-registries = ["docker.io"]`
+		- ...to have podman search work as per in the upstream instructions (Debian ships with ultra-safe defaults or something.)
+
+```
+podman run --rm -it fedora
+podman run --rm -it debian
+```
+
+Drop you into a one-off bare VM, it gets automatically cleaned up when you exit.
+
+```
+podman build -t agora .
+```
+
+Builds an 'agora' container if there is a [[Dockerfile]] in the path. If you want to force a 'clean' build, pass `--no-cache`; I needed this in the [[Agora Dockerfile]] because I was using `git clone` and this was failing to pull in the latest revisions.
+
+Then to run one interactively:
+
+```
+podman run -it agora
+```
+
+Or to run one detached (server like):
+
+```
+podman run -dt --name agora agora
+```
+
+Then you can:
+
+```
+podman attach agora
+```
+
+...to attach. CTRL-P CTRL-Q to detach gracefully.
