ProxyConfig
ProxyConfig
exposes proxy level configuration options. ProxyConfig
can be configured on a per-workload basis,
a per-namespace basis, or mesh-wide. ProxyConfig
is not a required resource; there are default values in place, which are documented
inline with each field.
NOTE: fields in ProxyConfig are not dynamically configured - changes will require restart of workloads to take effect.
For any namespace, including the root configuration namespace, it is only valid
to have a single workload selector-less ProxyConfig
resource.
For resources with a workload selector, it is only valid to have one resource selecting any given workload.
For mesh level configuration, put the resource in the root configuration namespace for your Istio installation without a workload selector:
apiVersion: networking.istio.io/v1beta1
kind: ProxyConfig
metadata:
name: my-proxyconfig
namespace: istio-system
spec:
concurrency: 0
image:
imageType: distroless
For namespace level configuration, put the resource in the desired namespace without a workload selector:
apiVersion: networking.istio.io/v1beta1
kind: ProxyConfig
metadata:
name: my-ns-proxyconfig
namespace: user-namespace
spec:
concurrency: 0
For workload level configuration, set the selector
field on the ProxyConfig
resource:
apiVersion: networking.istio.io/v1beta1
kind: ProxyConfig
metadata:
name: per-workload-proxyconfig
namespace: example
spec:
selector:
matchLabels:
app: ratings
concurrency: 0
image:
imageType: debug
If a ProxyConfig
CR is defined that matches a workload it will merge with its proxy.istio.io/config
annotation if present,
with the CR taking precedence over the annotation for overlapping fields. Similarly, if a mesh wide ProxyConfig
CR is defined and
meshConfig.DefaultConfig
is set, the two resources will be merged with the CR taking precedence for overlapping fields.

ProxyImage
The following values are used to construct proxy image url.
format: ${hub}/${image_name}/${tag}-${image_type}
,
example: docker.io/istio/proxyv2:1.11.1
or docker.io/istio/proxyv2:1.11.1-distroless
.
