# linkerd-control-plane
Linkerd gives you observability, reliability, and security
for your microservices — with no code change required.
![Version: 1.12.5](https://img.shields.io/badge/Version-1.12.5-informational?style=flat-square)
![Type: application](https://img.shields.io/badge/Type-application-informational?style=flat-square)
![AppVersion: edge-XX.X.X](https://img.shields.io/badge/AppVersion-edge--XX.X.X-informational?style=flat-square)
**Homepage:** <https://linkerd.io>
## Quickstart and documentation
You can run Linkerd on any Kubernetes 1.21+ cluster in a matter of seconds. See
the [Linkerd Getting Started Guide][getting-started] for how.
For more comprehensive documentation, start with the [Linkerd
docs][linkerd-docs].
## Prerequisite: linkerd-crds chart
Before installing this chart, please install the `linkerd-crds` chart, which
creates all the CRDs that the components from the current chart require.
## Prerequisite: identity certificates
The identity component of Linkerd requires setting up a trust anchor
certificate, and an issuer certificate with its key. These need to be provided
to Helm by the user (unlike when using the `linkerd install` CLI which can
generate these automatically). You can provide your own, or follow [these
instructions](https://linkerd.io/2/tasks/generate-certificates/) to generate new
ones.
Alternatively, both trust anchor and identity issuer certificates may be
derived from in-cluster resources. Existing CA (trust anchor) certificates
**must** live in a `ConfigMap` resource named `linkerd-identity-trust-roots`.
Issuer certificates **must** live in a `Secret` named
`linkerd-identity-issuer`. Both resources should exist in the control-plane's
install namespace. In order to use an existing CA, Linkerd needs to be
installed with `identity.externalCA=true`. To use an existing issuer
certificate, Linkerd should be installed with
`identity.issuer.scheme=kubernetes.io/tls`.
A more comprehensive description is in the [automatic certificate rotation
guide](https://linkerd.io/2.12/tasks/automatically-rotating-control-plane-tls-credentials/#a-note-on-third-party-cert-management-solutions).
Note that the provided certificates must be ECDSA certificates.
## Adding Linkerd's Helm repository
Included here for completeness-sake, but should have already been added when
`linkerd-base` was installed.
```bash
# To add the repo for Linkerd stable releases:
helm repo add linkerd https://helm.linkerd.io/stable
# To add the repo for Linkerd edge releases:
helm repo add linkerd-edge https://helm.linkerd.io/edge
```
The following instructions use the `linkerd` repo. For installing an edge
release, just replace with `linkerd-edge`.
## Installing the chart
You must provide the certificates and keys described in the preceding section,
and the same expiration date you used to generate the Issuer certificate.
```bash
helm install linkerd-control-plane -n linkerd \
--set-file identityTrustAnchorsPEM=ca.crt \
--set-file identity.issuer.tls.crtPEM=issuer.crt \
--set-file identity.issuer.tls.keyPEM=issuer.key \
linkerd/linkerd-control-plane
```
Note that you require to install this chart in the same namespace you installed
the `linkerd-base` chart.
## Setting High-Availability
Besides the default `values.yaml` file, the chart provides a `values-ha.yaml`
file that overrides some default values as to set things up under a
high-availability scenario, analogous to the `--ha` option in `linkerd install`.
Values such as higher number of replicas, higher memory/cpu limits and
affinities are specified in that file.
You can get ahold of `values-ha.yaml` by fetching the chart files:
```bash
helm fetch --untar linkerd/linkerd-control-plane
```
Then use the `-f` flag to provide the override file, for example:
```bash
helm install linkerd-control-plane -n linkerd \
--set-file identityTrustAnchorsPEM=ca.crt \
--set-file identity.issuer.tls.crtPEM=issuer.crt \
--set-file identity.issuer.tls.keyPEM=issuer.key \
-f linkerd2/values-ha.yaml
linkerd/linkerd-control-plane
```

## Prerequisite: linkerd-crds chart
Before installing this chart, please install the `linkerd-crds` chart, which
creates all the CRDs that the components from the current chart require.
## Prerequisite: identity certificates
The identity component of Linkerd requires setting up a trust anchor

instructions](https://linkerd.io/2/tasks/generate-certificates/) to generate new
ones.
Alternatively, both trust anchor and identity issuer certificates may be
derived from in-cluster resources. Existing CA (trust anchor) certificates
**must** live in a `ConfigMap` resource named `linkerd-identity-trust-roots`.
Issuer certificates **must** live in a `Secret` named
`linkerd-identity-issuer`. Both resources should exist in the control-plane's
install namespace. In order to use an existing CA, Linkerd needs to be
installed with `identity.externalCA=true`. To use an existing issuer
certificate, Linkerd should be installed with
`identity.issuer.scheme=kubernetes.io/tls`.
A more comprehensive description is in the [automatic certificate rotation
guide](https://linkerd.io/2.12/tasks/automatically-rotating-control-plane-tls-credentials/#a-note-on-third-party-cert-management-solutions).
Note that the provided certificates must be ECDSA certificates.

`linkerd-base` was installed.

You can get ahold of `values-ha.yaml` by fetching the chart files:

Then use the `-f` flag to provide the override file, for example:
```bash
helm install \

# linkerd2
Linkerd gives you observability, reliability, and security
for your microservices — with no code change required.
![Version: 0.1.0](https://img.shields.io/badge/Version-0.1.0-informational?style=flat-square)
![AppVersion: edge-XX.X.X](https://img.shields.io/badge/AppVersion-edge--XX.X.X-informational?style=flat-square)
**Homepage:** <https://linkerd.io>
## Quickstart and documentation
You can run Linkerd on any Kubernetes 1.16+ cluster in a matter of seconds. See
the [Linkerd Getting Started Guide][getting-started] for how.
For more comprehensive documentation, start with the [Linkerd
docs][linkerd-docs].
## Prerequisite: identity certificates
The identity component of Linkerd requires setting up a trust anchor
certificate, and an issuer certificate with its key. These need to be provided
to Helm by the user (unlike when using the `linkerd install` CLI which can
generate these automatically). You can provide your own, or follow [these
instructions](https://linkerd.io/2/tasks/generate-certificates/) to generate new
ones.
Note that the provided certificates must be ECDSA certificates.
## Adding Linkerd's Helm repository
```bash
# To add the repo for Linkerd2 stable releases:
helm repo add linkerd https://helm.linkerd.io/stable
# To add the repo for Linkerd2 edge releases:
helm repo add linkerd-edge https://helm.linkerd.io/edge
```
The following instructions use the `linkerd` repo. For installing an edge
release, just replace with `linkerd-edge`.
## Installing the chart
You must provide the certificates and keys described in the preceding section,
and the same expiration date you used to generate the Issuer certificate.
In this example we set the expiration date to one year ahead:
```bash
helm install \
--set-file identityTrustAnchorsPEM=ca.crt \
--set-file identity.issuer.tls.crtPEM=issuer.crt \
--set-file identity.issuer.tls.keyPEM=issuer.key \
--set identity.issuer.crtExpiry=$(date -d '+8760 hour' +"%Y-%m-%dT%H:%M:%SZ") \
linkerd/linkerd2
```
## Setting High-Availability
Besides the default `values.yaml` file, the chart provides a `values-ha.yaml`
file that overrides some default values as to set things up under a
high-availability scenario, analogous to the `--ha` option in `linkerd install`.
Values such as higher number of replicas, higher memory/cpu limits and
affinities are specified in that file.
You can get ahold of `values-ha.yaml` by fetching the chart files:
```bash
helm fetch --untar linkerd/linkerd2
```
Then use the `-f` flag to provide the override file, for example:
```bash
helm install \
--set-file identityTrustAnchorsPEM=ca.crt \
--set-file identity.issuer.tls.crtPEM=issuer.crt \
--set-file identity.issuer.tls.keyPEM=issuer.key \
--set identity.issuer.crtExpiry=$(date -d '+8760 hour' +"%Y-%m-%dT%H:%M:%SZ") \
-f linkerd2/values-ha.yaml
linkerd/linkerd2
```

## Extensions for Linkerd
The current chart installs the core Linkerd components, which grant you
reliability and security features. Other functionality is available through
extensions. Check the corresponding docs for each one of the following
extensions:
* Observability:
