Installing Iceshrimp using Podman and Quadlet

Quadlet is a feature of Podman that is kind of like Docker Compose, but is better integrated with systemd, just like whole Podman.

Requirements

• Podman 4.4+ with aardvark
• Git with LFS installed (if building your own images)

Preparations

Getting needed files

If you want to use prebuilt images:

GIT_LFS_SKIP_SMUDGE=1 git clone https://iceshrimp.dev/iceshrimp/iceshrimp.git --depth=1
mkdir -p $HOME/.config/containers/systemd
cp "iceshrimp/docs/examples/Podman (quadlet)"/* $HOME/.config/containers/systemd

Tweak quadlet files and change the image tag in $HOME/.config/containers/systemd/iceshrimp-web.container from latest to dev or pre if desired, and run docs/examples/Podman\ \(quadlet\)/volume-dir-creation.sh.

If you want to build your own images:

git lfs install
git clone https://iceshrimp.dev/iceshrimp/iceshrimp.git
mkdir -p $HOME/.config/containers/systemd
cp "iceshrimp/docs/examples/Podman (quadlet)"/* $HOME/.config/containers/systemd

Tweak quadlet files if needed, change content of Image: line in $HOME/.config/containers/systemd/iceshrimp-web.container to Image: localhost/iceshrimp/iceshrimp:latest, and run docs/examples/Podman\ \(quadlet\)/volume-dir-creation.sh.

.config

Edit .config/docker.env and fill it with the database credentials you want. Edit .config/default.yml and:

• Replace example database credentials with the ones you entered in .config/docker.env
• Change other configuration

Installation and first start

Choose a method, whether you chose to build the image yourself or not.

Pulling the image

podman pull $(grep -F "Image=" $HOME/.config/containers/systemd/iceshrimp-web.container | cut -d= -f2)
systemctl --user daemon-reload
systemctl --user start iceshrimp-web.service

Building the image

Enter Iceshrimp repo and run:

podman build . -t $(grep -F "Image=" $HOME/.config/containers/systemd/iceshrimp-web.container | cut -d= -f2) --ulimit nofile=16384:16384
systemctl --user daemon-reload
systemctl --user start iceshrimp-web.service

Starting Iceshrimp automatically

Run sudo loginctl enable-linger [user] and Iceshrimp will start automatically on boot. You don't need to, and in fact cannot enable Podman-generated systemd services.

Updating Iceshrimp

Pulling the image

podman pull $(grep -F "Image=" $HOME/.config/containers/systemd/iceshrimp-web.container | cut -d= -f2)
systemctl --user restart iceshrimp-web.service

Building the image

## Run git stash commands only if you have uncommitted changes
git stash
git pull
git stash pop
podman build . -t $(grep -F "Image=" $HOME/.config/containers/systemd/iceshrimp-web.container | cut -d= -f2) --ulimit nofile=16384:16384
systemctl --user restart iceshrimp-web.service

Post-install

If you are running Iceshrimp on a system with more than one CPU thread, you might want to set the clusterLimit config option to about half of your thread count, depending on your system configuration. Please note that each worker requires around 10 PostgreSQL connections, so be sure to set max_connections appropriately. To do this, change max_connections=n line in db/postgresql.conf, with n being (10 * no_workers) + 10, and run systemctl --user restart iceshrimp-db iceshrimp-web.
