Anbox Cloud Core

Learn about configurations >

• channel | string

  Default: 5.0/stable

  The snap channel to install from

• debug | boolean

  Enable verbose debugging for LXD

• disable_kernel_modules | boolean

  Disable the installation of the Anbox Cloud kernel modules. Useful in environments where the kernel modules are not needed (testing) or already part of the installed kernel.

• enable_manual_upgrade | boolean

  Enable support of manual charm upgrade via a Juju action. When the upgrade-charm hook will be executed, the charm will just update itself but not perform any further action. The upgrade then needs to be invoked manually via the upgrade action of the charm. This allows upgrades of individual units rather than upgrading all units together.

• extra_packages | string

  Space separated list of extra deb packages to install.

• https_host | string

  The host/ip to bind the REST service. You can set all interfaces ("[::]") If empty, each node sets its private IP

• https_port | int

  Default: 8443

  The port to bind the REST service. Default is 8443

• images_compression_algorithm | string

  Default: none

  Compression algorithms to be used for images. The supported compression algorithms: bzip2, gzip, lzma, xz or none.

• install_keys | string

  List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.

• install_sources | string

  List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.

• kernel_sysctl_pid_max | int

  Default: 4194304

  Sets the `kernel.pid_max` sysctl configuration option to the given value.

• nagios_context | string

  Default: juju

  Used by the nrpe subordinate charms. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup

• nvidia_driver_series | string

  Default: 550

  Series of the NVIDIA driver to install. On Ubuntu Focal, this will be forced to 535.

• package_status | string

  Default: install

  The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".

• public_interface | string

  Identifies which network interface to use for the public address

• shiftfs_enabled | boolean

  Enable support for shiftfs. This requires an Ubuntu kernel >= 5.0. Shiftfs can dramatically improve container startup times as it makes UID/GID shifts transparent. NOTE: Shiftfs support is turned off by default since 1.14 as it causes incorrect paths in /proc/*/maps files (and others) which break some Android applications.

• snapd_refresh | string

  How often snapd handles updates for installed snaps. The default (an empty string) is 4x per day. Set to "max" to check once per month based on the charm deployment date. You may also set a custom string as described in the 'refresh.timer' section here: https://forum.snapcraft.io/t/system-options/87

• subnet_prefix_length | int

  Default: 20

  Subnet prefix length determines the size of the subnet. It is expressed as a slash (/), followed by an integer between 1 through 128. The smaller the subnet prefix length, the more address you get to assign to containers in the subnet.

• telegraf_socket_listener_port | int

  Default: 8095

  Port where telegraf will listen for metrics to be published, in case it is configured in the same machine as LXD. NOTE - Try to avoid port 8094, because it could be already bound to tcp listener, installed by default in loopback network interface by telegraf charm.

• ua_source | string

  APT source to use instead of the automatic one generated from UA. Overrides UA source if both are set.

• ua_source_key | string

  Key ID to import to the APT keyring in order to access the specified source archive. Required if ua_source is set.

• ua_token | string

  Ubuntu Advantage token you have received with your license of Anbox Cloud

• ua_use_staging | boolean

  Use staging contracts API service

• use_prebuilt_nvidia_kernel_modules | boolean

  Install prebuilt and signed Nvidia kernel modules if set to true. If false, the charm will use the DKMS based Nvidia kernel module instead. This only applies to x86 based deployments. On Arm the DKMS kernel modules are always installed.
