This page explains how to change MAAS configuration options with the MAAS CLI.
Assuming you have successfully logged into the MAAS CLI, you can access configuration values using the maas $PROFILE maas set-config
command. This command is used to set MAAS configuration values. This command accepts keyword arguments. You must pass each argument as a key-value pair, with an equals sign between the key and the value, like this:
maas $PROFILE maas set-config key1=value1 key2=value key3=value3 ...
These keyword arguments must come after any positional arguments required by a specific command. The following configuration keywords are currently available:
- active_discovery_interval: Active subnet mapping interval. When enabled, each rack will scan subnets enabled for active mapping. This helps ensure discovery information is accurate and complete.
- boot_images_auto_import: Automatically import/refresh the boot images every 60 minutes.
- boot_images_no_proxy: Set no_proxy with the image repository address when MAAS is behind (or set with) a proxy. By default, when MAAS is behind (and set with) a proxy, it is used to download images from the image repository. In some situations (e.g. when using a local image repository) it doesn’t make sense for MAAS to use the proxy to download images because it can access them directly. Setting this option allows MAAS to access the (local) image repository directly by setting the no_proxy variable for the MAAS env with the address of the image repository.
- commissioning_distro_series: Default Ubuntu release used for commissioning.
- completed_intro: Marks if the initial intro has been completed.
- curtin_verbose: Run the fast-path installer with higher verbosity. This provides more detail in the installation logs.
- default_distro_series: Default OS release used for deployment.
- default_dns_ttl: Default Time-To-Live for the DNS. If no TTL value is specified at a more specific point this is how long DNS responses are valid, in seconds.
- default_min_hwe_kernel: Default Minimum Kernel Version. The default minimum kernel version used on all new and commissioned nodes.
- default_osystem: Default operating system used for deployment.
- default_storage_layout: Default storage layout. Storage layout that is applied to a node when it is commissioned. Available choices are*: ‘bcache’ (Bcache layout), ‘blank’ (No storage (blank) layout), ‘custom’ (Custom layout (from commissioning storage config)), ‘flat’ (Flat layout), ‘lvm’ (LVM layout), ‘vmfs6’ (VMFS6 layout), ‘vmfs7’ (VMFS7 layout).
- disk_erase_with_quick_erase: Use quick erase by default when erasing disks… This is not a secure erase; it wipes only the beginning and end of each disk.
- disk_erase_with_secure_erase: Use secure erase by default when erasing disks. Will only be used on devices that support secure erase. Other devices will fall back to full wipe or quick erase depending on the selected options.
- dns_trusted_acl: List of external networks (not previously known), that will be allowed to use MAAS for DNS resolution… MAAS keeps a list of networks that are allowed to use MAAS for DNS resolution. This option allows to add extra networks (not previously known) to the trusted ACL where this list of networks is kept. It also supports specifying IPs or ACL names.
- dnssec_validation: Enable DNSSEC validation of upstream zones. Only used when MAAS is running its own DNS server. This value is used as the value of ‘dnssec_validation’ in the DNS server config.
- enable_analytics: Enable Google Analytics in MAAS UI to shape improvements in user experience.
- enable_disk_erasing_on_release: Erase node disks prior to releasing. Forces users to always erase disks when releasing.
- enable_http_proxy: Enable the use of an APT or YUM and HTTP/HTTPS proxy. Provision nodes to use the built-in HTTP proxy (or user specified proxy) for APT or YUM. MAAS also uses the proxy for downloading boot images.

- enlist_commissioning: Whether to run commissioning during enlistment… Enables running all built-in commissioning scripts during enlistment.
- force_v1_network_yaml: Always use the legacy v1 YAML (rather than Netplan format, also known as v2 YAML) when composing the network configuration for a machine…
- hardware_sync_interval: Hardware Sync Interval. The interval to send hardware info to MAAS from hardware sync enabled machines, in systemd time span syntax.
- http_proxy: Proxy for APT or YUM and HTTP/HTTPS. This will be passed onto provisioned nodes to use as a proxy for APT or YUM traffic. MAAS also uses the proxy for downloading boot images. If no URL is provided, the built-in MAAS proxy will be used.
- kernel_opts: Boot parameters to pass to the kernel by default.
- maas_auto_ipmi_cipher_suite_id: MAAS IPMI Default Cipher Suite ID. The default IPMI cipher suite ID to use when connecting to the BMC via ipmitools Available choices are*: ‘’ (freeipmi-tools default), ‘12’ (12 - HMAC-MD5::MD5-128::AES-CBC-128), ‘17’ (17 - HMAC-SHA256::HMAC_SHA256_128::AES-CBC-128), ‘3’ (3 - HMAC-SHA1::HMAC-SHA1-96::AES-CBC-128), ‘8’ (8 - HMAC-MD5::HMAC-MD5-128::AES-CBC-128).
- maas_auto_ipmi_k_g_bmc_key: The IPMI K_g key to set during BMC configuration… This IPMI K_g BMC key is used to encrypt all IPMI traffic to a BMC. Once set, all clients will REQUIRE this key upon being commissioned. Any current machines that were previously commissioned will not require this key until they are recommissioned.
- maas_auto_ipmi_user: MAAS IPMI user… The name of the IPMI user that MAAS automatically creates during enlistment/commissioning.
- maas_auto_ipmi_user_privilege_level: MAAS IPMI privilege level. The default IPMI privilege level to use when creating the MAAS user and talking IPMI BMCs Available choices are*: ‘ADMIN’ (Administrator), ‘OPERATOR’ (Operator), ‘USER’ (User).

- node_timeout: Time, in minutes, until the node times out during commissioning, testing, deploying, or entering rescue mode… Commissioning, testing, deploying, and entering rescue mode all set a timeout when beginning. If MAAS does not hear from the node within the specified number of minutes the node is powered off and set into a failed status.
- ntp_external_only: Use external NTP servers only. Configure all region controller hosts, rack controller hosts, and subsequently deployed machines to refer directly to the configured external NTP servers. Otherwise only region controller hosts will be configured to use those external NTP servers, rack controller hosts will in turn refer to the regions’ NTP servers, and deployed machines will refer to the racks’ NTP servers.
- ntp_servers: Addresses of NTP servers. NTP servers, specified as IP addresses or hostnames delimited by commas and/or spaces, to be used as time references for MAAS itself, the machines MAAS deploys, and devices that make use of MAAS DHCP services.
- prefer_v4_proxy: Sets IPv4 DNS resolution before IPv6. If prefer_v4_proxy is set, the proxy will be set to prefer IPv4 DNS resolution before it attempts to perform IPv6 DNS resolution.
- prometheus_enabled: Enable sending stats to a prometheus gateway… Allows MAAS to send statistics to Prometheus. This requires the ‘prometheus_push_gateway’ to be set.
- prometheus_push_gateway: Address or hostname of the Prometheus push gateway… Defines the address or hostname of the Prometheus push gateway where MAAS will send data to.
- prometheus_push_interval: Interval of how often to send data to Prometheus (default*: to 60 minutes)… The internal of how often MAAS will send stats to Prometheus in minutes.
