Options

short	long	arguments	subsystem	description
-d		<domain list>	get/renew	Comma-separated list of domains to obtain a certificate for, or to otherwise apply. For multiple domains you can use multiple -d flags or enter a comma separated list of domains as a parameter. The first domain provided will be the subject CN of the certificate, and all domains will be Subject Alternative Names on the certificate. The first domain will also be used in some software user interfaces and as the file paths for the certificate and related material unless otherwise specified or you already have a certificate with the same name. In the case of a name collision it will append a number like 0001 to the file path name. (default: Ask)
	--apache		get/renew	Use the Apache plugin for authentication & installation
	--standalone		get/renew	Run a standalone webserver for authentication
	--nginx		get/renew	Use the Nginx plugin for authentication & installation
	--webroot		get/renew	Place files in a server's webroot folder for authentication
	--manual		get/renew	Obtain certificates interactively, or using shell script hooks
-n			get/renew	Run non-interactively
	--test-cert		get/renew	Obtain a test certificate from a staging server
	--dry-run		get/renew	Test "renew" or "certonly" without saving any certificates
	--agree-tos		account	Agree to the ACME server's Subscriber Agreement
-m		<email addr>	account	Email address for important account notifications
-h	--help		general	show a help message and exit
-c	--config	<config file>	general	path to config file (default: /etc/letsencrypt/cli.ini and ~/.config/letsencrypt/cli.ini)
-v	--verbose		general	This flag can be used multiple times to incrementally increase the verbosity of output, e.g. -vvv. (default: -2)
	--max-log-backups	<number>	general	Specifies the maximum number of backup logs that should be kept by Certbot's built in log rotation. Setting this flag to 0 disables log rotation entirely, causing Certbot to always append to the same log file. (default: 1000)
-n	--non-interactive --noninteractive		general	Run without ever asking for user input. This may require additional command line flags; the client will try to explain which ones are required if it finds one missing (default: False)
	--force-interactive		general	Force Certbot to be interactive even if it detects it's not being run in a terminal. This flag cannot be used with the renew subcommand. (default: False)
	--eab-kid	<EAB_KID>		Key Identifier for External Account Binding (default: None)
	--eab-hmac-key	<EAB_HMAC_KEY>		HMAC key for External Account Binding (default: None)
	--cert-name	<name>		Certificate name to apply. This name is used by Certbot for housekeeping and in file paths; it doesn't affect the content of the certificate itself. To see certificate names, run 'certbot certificates'. When creating a new certificate, specifies the new certificate's name. (default: the first provided domain or the name of an existing certificate on your system for the same domains)
	--dry-run			Perform a test run of the client, obtaining test (invalid) certificates but not saving them to disk. This can currently only be used with the 'certonly' and 'renew' subcommands. Note: Although --dry-run tries to avoid making any persistent changes on a system, it is not completely side-effect free: if used with webserver authenticator plugins like apache and nginx, it makes and then reverts temporary config changes in order to obtain test certificates, and reloads webservers to deploy and then roll back those changes. It also calls --pre-hook and --post-hook commands if they are defined because they may be necessary to accurately simulate renewal. --deploy-hook commands are not called. (default: False)
	--debug-challenges			After setting up challenges, wait for user input before submitting to CA (default: False)
	--preferred-challenges	<PREF_CHALLS>		A sorted, comma delimited list of the preferred challenges to use during authorization with the most preferred challenge listed first (Eg, "dns" or "http,dns"). Not all plugins support all challenges. See https://certbot.eff.org/docs/using.html#plugins for details. ACME Challenges are versioned, but if you pick "http" rather than "http-01", Certbot will select the latest version automatically. (default: [])
	--user-agent	<USER_AGENT>		Set a custom user agent string for the client. User agent strings allow the CA to collect high level statistics about success rates by OS, plugin and use case, and to know when to deprecate support for past Python versions and flags. If you wish to hide this information from the Let's Encrypt server, set this to "". (default: CertbotACMEClient/0.39.0 (certbot(-auto); OS_NAME OS_VERSION) Authenticator/XXX Installer/YYY (SUBCOMMAND; flags: FLAGS) Py/major.minor.patchlevel). The flags encoded in the user agent are: --duplicate, --force-renew, --allow-subset-of-names, -n, and whether any hooks are set.
	--user-agent-comment	<comment>		Add a comment to the default user agent string. May be used when repackaging Certbot or calling it from another tool to allow additional statistical data to be collected. Ignored if --user-agent is set. (Example: Foo-Wrapper/1.0) (default: None)
	--keep-until-expiring --keep --reinstall		automation	If the requested certificate matches an existing certificate, always keep the existing one until it is due for renewal (for the 'run' subcommand this means reinstall the existing certificate). (default: Ask)
	--expand		automation	If an existing certificate is a strict subset of the requested names, always expand and replace it with the additional names. (default: Ask)
	--version		automation	show program's version number and exit
	--force-renewal --renew-by-default		automation	If a certificate already exists for the requested domains, renew it now, regardless of whether it is near expiry. (Often --keep-until-expiring is more appropriate). Also implies --expand. (default: False)
	--renew-with-new-domains		automation	If a certificate already exists for the requested certificate name but does not match the requested domains, renew it now, regardless of whether it is near expiry. (default: False)
	--reuse-key		automation	When renewing, use the same private key as the existing certificate. (default: False)
	--allow-subset-of-names		automation	When performing domain validation, do not consider it a failure if authorizations can not be obtained for a strict subset of the requested domains. This may be useful for allowing renewals for multiple domains to succeed even if some domains no longer point at this system. This option cannot be used with --csr. (default: False)
	--agree-tos		automation	Agree to the ACME Subscriber Agreement (default: Ask)
	--duplicate		automation	Allow making a certificate lineage that duplicates an existing one (both can be renewed in parallel) (default: False)
	--os-packages-only		automation	(certbot-auto only) install OS package dependencies and then stop (default: False)
	--no-self-upgrade		automation	(certbot-auto only) prevent the certbot-auto script from upgrading itself to newer released versions (default: Upgrade automatically)
	--no-bootstrap		automation	(certbot-auto only) prevent the certbot-auto script from installing OS-level dependencies (default: Prompt to install OS-wide dependencies, but exit if the user says 'No')
	--no-permissions-check		automation	(certbot-auto only) skip the check on the file system permissions of the certbot-auto script (default: False)
-q	--quiet		automation	Silence all output except errors. Useful for automation via cron. Implies --non-interactive. (default: False)
	--rsa-key-size	<N>	security	Size of the RSA key. (default: 2048)
	--must-staple		security	Adds the OCSP Must Staple extension to the certificate. Autoconfigures OCSP Stapling for supported setups (Apache version >= 2.3.3 ). (default: False)
	--redirect		security	Automatically redirect all HTTP traffic to HTTPS for the newly authenticated vhost. (default: Ask)
	--no-redirect		security	Do not automatically redirect all HTTP traffic to HTTPS for the newly authenticated vhost. (default: Ask)
	--hsts		security	Add the Strict-Transport-Security header to every HTTP response. Forcing browser to always use SSL for the domain. Defends against SSL Stripping. (default: None)
	--uir		security	Add the "Content-Security-Policy: upgrade-insecure-requests" header to every HTTP response. Forcing the browser to use https:// for every http:// resource. (default: None)
	--staple-ocsp		security	Enables OCSP Stapling. A valid OCSP response is stapled to the certificate that the server offers during TLS. (default: None)
	--strict-permissions		security	Require that all configuration files are owned by the current user; only needed if your config is somewhere unsafe like /tmp/ (default: False)
	--auto-hsts		security	Gradually increasing max-age value for HTTP Strict Transport Security security header (default: False)
