global.proxy.protocolDetectionTimeout10msAutomatic protocol detection uses a set of heuristics to determine whether the connection is using TLS or not (on the server side), as well as the application protocol being used (e.g., http vs tcp). These heuristics rely on the client sending the first bits of data. For server first protocols like MySQL, MongoDB, etc., Envoy will timeout on the protocol detection after the specified period, defaulting to non mTLS plain TCP traffic. Set this field to tweak the period that Envoy will wait for the client to send the first bits of data. (MUST BE >=1ms)

global.policyCheckFailOpenfalsepolicyCheckFailOpen allows traffic in cases when the mixer policy service cannot be reached. Default is false which means the traffic is denied when the client is unable to connect to Mixer.

global.arch.ppc64le2
global.oneNamespacefalseWhether to restrict the applications namespace the controller manages; If not set, controller watches all namespaces
global.defaultNodeSelector{}Default node selector to be applied to all deployments so that all pods can be constrained to run a particular nodes. Each component can overwrite these default values by adding its node selector block in the relevant section below and setting the desired values.

global.priorityClassName""
global.useMCPtrueUse the Mesh Control Protocol (MCP) for configuring Mixer and Pilot. Requires galley (--set galley.enabled=true).
global.trustDomain""
global.meshID""Mesh ID means Mesh Identifier. It should be unique within the scope where meshes will interact with each other, but it is not required to be globally/universally unique. For example, if any of the following are true, then two meshes must have different Mesh IDs: - Meshes will have their telemetry aggregated in one place - Meshes will be federated together - Policy will be written referencing one mesh from the other If an administrator expects that any of these conditions may become true in the future, they should ensure their meshes have different Mesh IDs assigned. Within a multicluster mesh, each cluster must be (manually or auto) configured to have the same Mesh ID value. If an existing cluster 'joins' a multicluster mesh, it will need to be migrated to the new mesh ID. Details of migration TBD, and it may be a disruptive operation to change the Mesh ID post-install. If the mesh admin does not specify a value, Istio will use the value of the mesh's Trust Domain. The best practice is to select a proper Trust Domain value.
global.outboundTrafficPolicy.modeALLOW_ANY
global.sds.enabledfalseSDS enabled. IF set to true, mTLS certificates for the sidecars will be distributed through the SecretDiscoveryService instead of using K8S secrets to mount the certificates.
global.sds.udsPath""
