Hosts join the cluster by running the installer, which shows a code and
waits until the request is approved under Hosts > Add host in the web
interface or with clusterioctl host approve. An admin can pass their
user token to the installer to approve the host right away. The token
is only used for that and is not saved.
The controller only accepts hosts that have a record, and only
approving a host creates one. Revoking a host deletes its record, so
its token can no longer be used to reconnect. Hosts that have connected
before keep working.
Removes host generate-token, revoke-token and create-config from
clusterioctl, bootstrap generate-host-token, the host token messages and
the core.host.generate_token, revoke_token and create_config
permissions, which are also stripped from stored roles. Adds
clusterioctl host pending, approve, reject and revoke, and the
core.host.approve and core.host.revoke permissions.
Standalone installs add the host to the controller database directly,
since the controller is not running during the install.
The migration from phin to fetch in #755 was hampred by the lack of an
option to set the CA when using fetch. This meant places that used phin
to talk to the controller with the tlsCa option could not be migrated to
use fetch.
Remove the tlsCa option to unblock this dependency. The replacement for
this option is to set the NODE_EXTRA_CA_CERTS environment variable to a
path to the certificate file instead, which works with fetch.
The role of a slave as a host for Factorio servers is not well reflected
in its name and has caused confusion among users. Rename slave to host
to better reflect its role as a host of Factorio servers.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
Simplify the the way markdown files are formatted to make them easier to
author without editors that do auto line breaking, and make the diffs
from them simpler to read.
The automatic creation of a self-signed certificate while nice presents
several problems. To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.
To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server. These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.
For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly. This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
