Install

bldr has two halves: a node, which is a daemon that stores content and runs containers, and the bldr CLI, which talks to it. You need both, though they are usually the same machine to start with.

Install the package

sudo dpkg -i bldr_<version>_amd64.deb

That gives you /usr/bin/bldr and /usr/bin/bldr-daemon, a default config at /etc/bldr/node.yml, and a systemd user unit.

Start your node

The daemon runs as you, not as root, so each user gets their own node and their own store.

systemctl --user enable --now bldr-daemon

If you want it to survive logout:

loginctl enable-linger $USER

Check it

bldr info

[G] Node info
    peer ID:        12D3KooW...
    peers:          1
    bootstrapped:   yes

If that prints, the CLI found the daemon and you are ready. If it says it cannot connect, the daemon is not running: systemctl --user status bldr-daemon will say why.

Next: make a workspace.
