Kubernetes Core

bgp-service-cluster-ips | string

Space-separated list of service cluster CIDRs to advertise over BGP. These will be passed to the .spec.serviceClusterIPs field of the default BGPConfiguration in Calico. Example value: ”10.0.0.0/24 10.0.1.0/24”

bgp-service-external-ips | string

Space-separated list of service external CIDRs to advertise over BGP. These will be passed to the .spec.serviceExternalIPs field of the default BGPConfiguration in Calico. Example value: ”10.0.0.0/24 10.0.1.0/24”

bgp-service-loadbalancer-ips | string

Space-separated list of service load-balancer CIDRs to advertise over BGP. These will be passed to the .spec.serviceLoadBalancerIPs field of the default BGPConfiguration in Calico. Example value: ”10.0.0.0/24 10.0.1.0/24”

cidr | string

Default: 192.168.0.0/16

Network CIDR assigned to Calico. This is applied to the default Calico pool, and is also communicated to the Kubernetes charms for use in kube-proxy configuration. Calico assigns IP addresses to Kubernetes nodes in blocks of 64 addresses. It is recommended to make the Calico network large enough to assign at least one 64 address block to each kubernetes-control-plane and kubernetes-worker unit.

disable-vxlan-tx-checksumming | boolean

Default: True

When set to true, if VXLAN encapsulation is in use, then the charm will disable TX checksumming on the vxlan.calico network interface. This works around an upstream issue in Calico: https://github.com/projectcalico/calico/issues/3145

global-as-number | int

Default: 64512

Global AS number.

global-bgp-peers | string

Default: []

List of global BGP peers. Each BGP peer is specified with an address and an as-number. Example value: "[{address: 10.0.0.1, as-number: 65000}, {address: 10.0.0.2, as-number: 65001}]"

ignore-loose-rpf | boolean

Enable or disable IgnoreLooseRPF for Calico Felix. This is only used when rp_filter is set to a value of 2.

image-registry | string

Default: rocks.canonical.com:443/cdk

Source registry of Calico images. By setting to a value, each image listed in the releases manifest has its image-registry replaced.

ipip | string

Default: Never

IPIP encapsulation mode. Must be one of "Always", "CrossSubnet", or "Never". This is incompatible with VXLAN encapsulation. If VXLAN encapsulation is enabled, then this must be set to "Never".

manage-pools | boolean

Default: True

If true, a default pool is created using the cidr and ipip charm configuration values. Warning: When manage-pools is enabled, the charm will delete any pools that are unrecognized.

nat-outgoing | boolean

Default: True

NAT outgoing traffic

node-to-node-mesh | boolean

Default: True

When enabled, each Calico node will peer with every other Calico node in the cluster.

release | string

Version of Calico to deploy

route-reflector-cluster-ids | string

Default: {}

Mapping of unit IDs to route reflector cluster IDs. Assigning a route reflector cluster ID allows the node to function as a route reflector. Example value: "{0: 224.0.0.1, 2: 224.0.0.1}"

subnet-as-numbers | string

Default: {}

Mapping of subnets to AS numbers, specified as YAML. Each Calico node will be assigned an AS number based on the entries in this mapping. Example value: "{10.0.0.0/24: 64512, 10.0.1.0/24: 64513}" If a node's IP matches any of the specified subnets, then the corresponding AS number is used instead of the global one. If a node's IP matches no subnets, then the global AS number will be used instead. If a node's IP matches multiple subnets, then the most specific subnet will be used, e.g. a /24 subnet will take precedence over a /16.

subnet-bgp-peers | string

Default: {}

Mapping of subnets to lists of BGP peers. Each BGP peer is specified with an address and an as-number. Example value: "{10.0.0.0/24: [{address: 10.0.0.1, as-number: 65000}, {address: 10.0.0.2, as-number: 65001}], 10.0.1.0/24: [{address: 10.0.1.1, as-number: 65002}]}" If a node's IP matches multiple subnets, then peerings will be added for each matched subnet.

unit-as-numbers | string

Default: {}

Mapping of unit IDs to AS numbers, specified as YAML. Each Calico node will be assigned an AS number based on the entries in this mapping. Example value: "{0: 64512, 1: 64513}" This takes precedence over global-as-number and subnet-as-numbers.

unit-bgp-peers | string

Default: {}

Mapping of unit IDs to lists of BGP peers. Each BGP peer is specified with an address and an as-number. Example value: "{0: [{address: 10.0.0.1, as-number: 65000}, {address: 10.0.0.2, as-number: 65001}], 1: [{address: 10.0.1.1, as-number: 65002}]}"

veth-mtu | int

Set veth MTU size. This should be set to the MTU size of the base network. If VXLAN is enabled, then the charm will automatically subtract 50 from the specified MTU size. If IPIP is enabled, then the charm will automatically subtract 20 from the specified MTU size.

vxlan | string

Default: Never

VXLAN encapsulation mode. Must be one of "Always", "CrossSubnet", or "Never". This is incompatible with IPIP encapsulation. If IPIP encapsulation is enabled, then this must be set to "Never".
