Uninstall ​

A server installed with an install command ​

Use theseus-node uninstall. It also tells the control plane, so the server shows as uninstalled there and can be installed again later with a new install command.

bash
sudo theseus-node uninstall              # asks you to type "uninstall"
sudo theseus-node uninstall --keep-data  # keep the stack directory and Docker volumes
sudo theseus-node uninstall --yes        # no question (automation)

It:

  1. stops and disables theseus-node;
  2. takes the stack down: without --keep-data it deletes the containers and the data volumes (./theseus uninstall); with --keep-data it only stops them (./theseus down);
  3. logs Docker out of the Theseus registry;
  4. without --keep-data, removes the stack directory (/opt/theseus);
  5. tells the control plane;
  6. removes theseus-node itself: its service, binary, /etc/theseus-node and /var/lib/theseus-node.

If the stack cannot be taken down, nothing is removed and theseus-node is started again.

Not removed: Docker itself, the vm.max_map_count setting in /etc/sysctl.d/99-theseus.conf, and any /opt/theseus.prev-* directories from earlier re-installs.

With --keep-data, a later install picks up the same data.

We can also uninstall a server from the control plane, with or without keeping data. Ask us.

A stack without theseus-node ​

bash
cd /opt/theseus && sudo ./theseus uninstall

It asks you to type DELETE, then removes the containers and all data volumes (alerts, users, agent registrations). theseus.env and runtime/ are kept; delete the directory yourself if you no longer need them.

Two servers ​

Uninstall the application server first, then the core.

Endpoints ​

Removing the server does not remove agents from endpoints. Remove them first from the Agents page with Uninstall from the host first, or on each machine; see Disable, enable, remove.
