# Usage info
usage() {
cat << HEREDOC
USAGE: kickstart.sh [options]
where options include:
--non-interactive Do not prompt for user input. (default: prompt if there is a controlling terminal)
--interactive Prompt for user input even if there is no controlling terminal.
--dont-start-it Do not start the agent by default (only for static installs or local builds)
--dry-run Report what we would do with the given options on this system, but don’t actually do anything.
--release-channel Specify the release channel to use for the install (default: ${DEFAULT_RELEASE_CHANNEL})
--stable-channel Equivalent to "--release-channel stable"
--nightly-channel Equivalent to "--release-channel nightly"
--no-updates Do not enable automatic updates (default: enable automatic updates using the best supported scheduling method)
--auto-update Enable automatic updates.
--auto-update-type Specify a particular scheduling type for auto-updates (valid types: systemd, interval, crontab)
--disable-telemetry Opt-out of anonymous statistics.
--native-only Only install if native binary packages are available.
--static-only Only install if a static build is available.
--build-only Only install using a local build.
--disable-cloud Disable support for Netdata Cloud (default: detect)
--require-cloud Only install if Netdata Cloud can be enabled. Overrides --disable-cloud.
--install-prefix <path> Specify an installation prefix for local builds (default: autodetect based on system type).
--old-install-prefix <path> Specify an old local builds installation prefix for uninstall/reinstall (if it's not default).
--install-version <version> Specify the version of Netdata to install.
--claim-token Use a specified token for claiming to Netdata Cloud.
--claim-rooms When claiming, add the node to the specified rooms.
--claim-* Specify other options for the claiming script.
--no-cleanup Don't do any cleanup steps. This is intended to help with debugging the installer.
--local-build-options Specify additional options to pass to the installer code when building locally. Only valid if --build-only is also specified.
--static-install-options Specify additional options to pass to the static installer code. Only valid if --static-only is also specified.
--offline-architecture Limit an offline install source being prepared with --prepare-offline-install-source to only include the specified static build architecture.
The following options are mutually exclusive and specifiy special operations other than trying to install Netdata normally or update an existing install:
--reinstall If there is an existing install, reinstall it instead of trying to update it. If there is no existing install, install netdata normally.
--reinstall-even-if-unsafe If there is an existing install, reinstall it instead of trying to update it, even if doing so is known to potentially break things. If there is no existing install, install Netdata normally.
--reinstall-clean If there is an existing install, uninstall it before trying to install Netdata. Fails if there is no existing install.
--uninstall Uninstall an existing installation of Netdata. Fails if there is no existing install.
--claim-only If there is an existing install, only try to claim it without attempting to update it. If there is no existing install, install and claim Netdata normally.
--repositories-only Only install repository configuration packages instead of doing a full install of Netdata. Automatically sets --native-only.
--prepare-offline-install-source Instead of installing the agent, prepare a directory that can be used to install on another system without needing to download anything.
Additionally, this script may use the following environment variables:
TMPDIR: Used to specify where to put temporary files. On most systems, the default we select
automatically should be fine. The user running the script needs to both be able to
write files to the temporary directory, and run files from that location.
ROOTCMD: Used to specify a command to use to run another command with root privileges if needed. By
default we try to use sudo, doas, or pkexec (in that order of preference), but if
you need special options for one of those to work, or have a different tool to do
the same thing on your system, you can specify it here.
DISABLE_TELEMETRY If set to a value other than 0, behave as if \`--disable-telemetry\` was specified.
