Deploy the Armory Scale Agent Service Using a Helm Chart

Use a Helm chart to deploy the Armory Scale Agent service to your Kubernetes cluster.

Chart overview

Exposes all settings for installing the Armory Scale Agent service.
Enables you to easily deploy the Armory Scale Agent service with default configuration using a single command.
Gives you the ability to customize the service settings in a file or via the command line.

Connecting to Armory Cloud services is enabled by default. Armory Cloud services is required for some features to function and affects how you configure the Armory Scale Agent service installation. If you want to connect to Armory Cloud services, you must include your Armory Cloud client ID and secret. You can disable connecting to Armory Cloud services by setting a gPRC URL instead of providing your Armory Cloud services credentials.

Before you begin

Ensure you have completed the following steps before you install the Armory Scale Agent using the Helm chart:

You have installed the Clouddriver plugin.
You are familiar with Helm and have installed v3.6.3+.
You have added or updated the Armory charts repo in your Kubernetes environment.

To add the Armory chart repo, execute the following command:
```
helm repo add armory-charts http://armory.jfrog.io/artifactory/charts
```
If you have previously added the chart repo, update it with the following commands:
```
helm repo update
helm upgrade armory-agent armory-charts/agent-k8s-full
```
You are familiar with the various use cases for deploying Scale Agent services to your Kubernetes clusters.

Quickstart

Run one of the following commands:

If you want to connect to Armory Cloud services:

You must include your Armory Cloud clientId and clientSecret credentials.

helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set hub.auth.armory.clientId=<your-clientID>,hub.auth.armory.secret=<your-clientSecret>

If you don’t want to connect to Armory Cloud services:

You must include your gPRC endpoint, such as localhost:9090.

helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set config.clouddriver.grpc=<endpoint>

Command options:

--create-namespace: (Optional) Creates the namespace if not present. See the Helm install docs.
--namespace=<agent-namespace>: (Required) The namespace where you install the Armory Scale Agent, which is also the deployment target for your app.

Before you start, make sure:

Each account has a kubeconfig file that grants access to the deployment target cluster. If you use Amazon EKS, you can run the following command:
```
aws eks update-kubeconfig --name <target-cluster>
```
Each account has a kubeconfig file and a secret created from that file. For example:
```
kubectl create secret generic kubeconfig --from-file=<path>/.kube/config -n <namespace>
```
See the kubectl create secret generic docs for command details.

Run one of the following commands:

If you want to connect to Armory Cloud services:

You must set your Armory Cloud clientId and clientSecret credentials.

You must set your kubeconfig file and secret. <kubeconfig> is the name of the file you used when you created the secret. If you used --from-file=<path>/.kube/config, the value of <kubeconfig> is config.

helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set hub.auth.armory.clientId=<your-clientID> \
,hub.auth.armory.secret=<your-clientSecret> \
,kubeconfigs.<account-name>.file=<kubeconfig> \
,kubeconfigs.<account-name>.secret=<secret>

If you don’t want to connect to Armory Cloud services:

You must include your gPRC endpoint, such as localhost:9090.

You must set your kubeconfig file and secret. <kubeconfig> is the name of the file you used when you created the secret. If you used --from-file=<path>/.kube/config, the value of <kubeconfig> is config.
```
helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set config.clouddriver.grpc=<endpoint> \
,kubeconfigs.<account-name>.file=<kubeconfig> \
,kubeconfigs.<account-name>.secret=<secret>
```

Command options:

--create-namespace: (Optional) Creates the namespace if not present. See the Helm install docs.
--namespace=<agent-namespace>: (Required) The namespace where you install the Armory Scale Agent, which is also the deployment target for your app.

Confirm success

Create a pipeline with a Deploy manifest stage. You should see your target cluster available in the Accounts list. Deploy a static manifest.

Set proxy settings

The env parameters are optional and only need to be used if Armory CD is behind an HTTP(S) proxy. If you need to set more than one of the env parameters, you must increment the index value for the parameters. For example: env[0].name="HTTP_PROXY, env[1].name="HTTPS_PROXY", and env[2].name="NO_PROXY".

helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set env[0].name=”HTTP_PROXY”,env[0].value="<hostname>:<port>" \
,env[1].name=”HTTPS_PROXY”,env[1].value="<hostname>:<port>" \
,env[2].name=”NO_PROXY”,env[2].value="localhost,127.0.0.1,*.spinnaker"

Alternatively, you can create a values.yaml file to include the parameters:

env:
  - name: HTTP_PROXY
    value: <hostname>:<port>
  - name: HTTPS_PROXY
    value: <hostname>:<port>
  - name: NO_PROXY
    value: localhost,127.0.0.1,*.spinnaker

With the file, you can avoid setting individual env parameters in the helm install command. Instead include the --values parameter as part of the Helm install command:

--values=<path>/values.yaml

Set a custom Agent image registry

If you need to download the Armory Scale Agent image from a different registry, you can specify that repository using the following settings:

--set image.repository=<repo-name>,image.imagePullPolicy=IfNotPresent, /
image.imagePullSecrets=<secret>

Alternatively, you can create a values.yaml file to include the settings:

image:
  repository: <repo-name>
  imagePullPolicy: IfNotPresent
  imagePullSecrets: <secret>

Include the --values parameter as part of the Helm install command:

--values=<path>/values.yaml

Custom configuration

If you need greater flexibility, you can override any supported configuration option, either by setting values using the command line or by setting values in an armory-agent.yml file.

Set config values using the command line

You can update configuration options via the command line by using --set config.<option>. For example, if you want to set logging.level to debug, use --set config.logging.level=debug to do that.

Set config in a file

You can also override default settings in your own armory-agent.yml file. For example, if you want to modify the default logging settings, create an armory-agent.yml file with the following content:

logging:
  file: "my-log"
  format: "json"
  level: "debug"

Note that you do not use “config” in the armory-agent file even though you do when setting config using the command line.

Then use the --set-file option in the Helm install command:

1

4


helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set-file agentyml=<path-to>/armory-agent.yml

You can pass in an armory-agent.yml file and also override values on the command line:

1
2
3
4
5


helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set-file agentyml=<path-to>/armory-agent.yml \
--set config.logging.level=debug

The difference between `values.yaml` and `armory-agent.yml`

armory-agent.yml: any supported configuration option listed in the Armory Scale Agent Options configuration option section.

values.yaml: environmental values such as proxy settings and image repository.

You can use both files. For example:

1
2
3
4
5


helm install armory-agent armory-charts/agent-k8s-full \
--create-namespace \
--namespace=<agent-namespace> \
--set-file agentyml=<path-to>/armory-agent.yml \
--values=<path-to>/values.yaml

Examples

,image.imagePullSecrets=regcred \
,env[0].name=”HTTP_PROXY”,env[0].value="corp.proxy.com:8080" \
,env[1].name=”HTTPS_PROXY”,env[1].value="corp.proxy.com:443" \
,env[2].name=”NO_PROXY”,env[2].value="localhost,127.0.0.1,*.spinnaker"

The same custom configuration in a values.yaml file:

image:
  repository: private-reg/agent-k8s
  imagePullPolicy: IfNotPresent
  imagePullSecrets: regcred

env:
