Deploy Options

Pixie offers the following deploy options:

• Annotate Pixie's resources
• Label Pixie's resources
• Deploy to a subset of nodes
• Provide a custom cluster name
• Configure Pixie's memory usage
• Set the data access mode
• Select metadata storage option
• Configure a custom image registry
• Set a PEM flag

To see the full set of deploy options, install the Pixie CLI and run px deploy --help.

When deploying Pixie, you have the option of adding one or more custom annotations to the Kubernetes objects deployed by Pixie.

To annotate Pixie's resources when deploying with the Pixie CLI, use the --annotations flag:

px deploy --annotations=key1=value1,key2=value2

To annotate Pixie's resources when deploying with Helm, use the annotations field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set annotations=key1=value1,key2=value2

When deploying Pixie, you have the option of adding one or more custom labels to the Kubernetes objects deployed by Pixie. Certain labels are reserved for internal use by Pixie. The following are reserved label strings that may not be used:

• "vizier-bootstrap"
• “component"
• “vizier-updater-dep"
• “app"

To label Pixie's resources when deploying with the Pixie CLI, use the --labels flag:

px deploy --labels=key1=value1,key2=value2

To label Pixie's resources when deploying with Helm, use the labels field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set labels=key1=value1,key2=value2

When deploying Pixie, you have the option of selecting which nodes Pixie will be deployed to in your cluster. For example, Pixie runs on Linux nodes only, so you would use this option to deploy Pixie to clusters with mixed node types.

To deploy Pixie to a subset of the nodes in your cluster:

1. Label the target nodes with pixie=allowed.

2. Add a nodeSelector to Pixie's vizier-pem datacollector pods during deployment:

When deploying with the Pixie CLI, use the --patches flag:

px deploy --patches='vizier-pem:{\"spec\":{\"template\":{\"spec\":{\"nodeSelector\":{\"pixie\": \"allowed\"}}}}}'

When deploying with Helm, use the patches.vizier-pem field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set patches.vizier-pem='\{\"spec\"\: \{\"template\"\: \{\"spec\"\: \{ \"nodeSelector\"\: \{\"pixie\"\: \"allowed\" \}\}\}\}\}'

When deploying Pixie, you have the option of providing a custom cluster name. If you do not provide a cluster name, the name will be taken from the current kubeconfig.

To provide a custom cluster name when deploying with the Pixie CLI, use the --cluster_name flag:

# Deploy Pixie in your K8s cluster and use the provided name for the cluster.
px deploy --cluster_name=<CLUSTER_NAME>

To provide a custom cluster name when deploying with Helm, use the clusterName field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --set clusterName=<CLUSTER_NAME> --namespace pl --create-namespace

When deploying Pixie, you have three options for configuring PEM memory usage:

• Set PEM pod memory limit
• Set PEM pod memory request
• Set data table storage limit

For more information about these options, please refer to the Tuning Memory Usage page.

The default memory limit is 2Gi per PEM. The lowest recommended value is 1Gi per PEM. 1Gi is not a suitable limit for a cluster with high throughput, but it is suitable for a small cluster with limited resources.

To set Pixie's memory limit when deploying with the Pixie CLI, use the --pem_memory_limit flag:

px deploy --pem_memory_limit=1Gi

To set Pixie's memory limit when deploying with Helm, use the pemMemoryLimit field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set pemMemoryLimit=1Gi

By default, the PEM's memory request will be the same as the limit. When deploying Pixie, you can specify a different memory request than limit. This flag is useful for clusters in which the PEM pods are pending because there is not enough memory for them to be scheduled on the node.

To set Pixie's memory request when deploying with the Pixie CLI, use the --pem_memory_request flag:

px deploy --pem_memory_request=1Gi

To set Pixie's memory request when deploying with Helm, use the pemMemoryRequest field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set pemMemoryRequest=1Gi

This is an advanced option that most developers shouldn't need. For more discussion see the Tuning Memory Usage page.

To set Pixie's data store memory limit when deploying with the Pixie CLI, use the --pem_flags flag:

px deploy --pem_flags="PL_TABLE_STORE_DATA_LIMIT_MB=1000"

To set Pixie's data store memory limit when deploying with Helm, use the dataCollectorParams.customPEMFlags.PL_TABLE_STORE_DATA_LIMIT_MB field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set dataCollectorParams.customPEMFlags.PL_TABLE_STORE_DATA_LIMIT_MB=750

When deploying Pixie, you have the option of setting the data access mode. This mode controls what data can be displayed when executing a PxL script to query Pixie platform telemetry data. Pixie offers two data access modes:

• Full (default): The user has full data access, and Pixie does not redact any collected data from the user during script execution.

• Restricted: The user has restricted data access. Pixie will redact all columns that may potentially contain sensitive data (e.g. request/response bodies and headers). All rows in the column will be redacted, regardless of whether they do or do not actually contain PII. Metadata about these columns, such as length, will still be queryable.

If no data access mode is specified when deploying Pixie, the deploy assumes Full as default.

To set the data access mode when deploying with the Pixie CLI, use the --data_access flag:

px deploy --data_access=(Full|Restricted)

To set the data access mode when deploying with Helm, use the dataAccess field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set dataAccess=(Full|Restricted)

You may also directly update the dataAccess field in your values.yaml file.

By default, Pixie uses a persistent volume to store 24 hours' worth of Kubernetes metadata updates.

For clusters that don't support persistent volumes, we have an alternative mode that uses the etcd operator.

To deploy using the etcd operator using px deploy, use the --use_etcd_operator flag.

px deploy --use_etcd_operator

To deploy with Helm using the etcd operator, use the --useEtcdOperator flag.

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set pixie-chart.useEtcdOperator=true

By default, Pixie uses images hosted on gcr.io. Pixie allows you to specify a custom image registry for clusters which may not have access to gcr.io or for users who simply want to host their own images.

1. Download the Vizier artifacts:

curl https://storage.googleapis.com/pixie-dev-public/vizier/latest/vizier_yamls.tar | tar x
cd yamls

2. Determine whether you'd like to deploy Pixie with or without etcd. We recommend installing Pixie without etcd as long as your cluster supports Pixie creating and using PVs.

To list the images required to deploy Pixie without etcd (Recommended):

cat images/vizier_image_list.txt

To list the images required to deploy Pixie with etcd:

cat vizier_etcd_image_list.txt

3. Collect and publish the images listed in Step 2 to your custom registry.

Note that Pixie expects hosted images to adhere to the following format: ${custom_registry}/${defaultImagePath | sed 's/\//-/g'}. In other words, Pixie will expect your images to be hosted on your registry, where the image name in your registry is Pixie's full image path with any / replaced with -. For example: gcr.io/pixie-oss/pixie-dev/vizier/metadata_server_image:latest should pushed to $registry/gcr.io-pixie-oss-pixie-dev-vizier-metadata_server_image:latest.

Pixie depends on OLM to deploy its operator. The required OLM images are listed below:

quay.io/operator-framework/olm
quay.io/operator-framework/olm@sha256:b706ee6583c4c3cf8059d44234c8a4505804adcc742bcddb3d1e2f6eff3d6519
quay.io/operator-framework/configmap-operator-registry:latest

2. You will need to build your own OLM bundle.

3. Download opm:

opm index export --index gcr.io/pixie-oss/pixie-prod/operator/bundle_index:0.0.1

3. Find the current operator version listed in the downloaded/pixie-operator/package.yaml file.

4. Locate the operator's csv in the downloaded/pixie-operator/<version>/csv.yaml file. Remove the replaces line and update the image tag for gcr.io/pixie-oss/pixie-prod/operator/operator_image:<version> to your hosted image.

5. Next, build your bundle by running the following:

opm alpha bundle generate --package pixie-operator --channels stable --default stable --directory downloaded/pixie-operator/<version>
docker build -t ${registry}/bundle:<version> -f bundle.Dockerfile .
docker push ${registry}/bundle:<version>
opm index add --bundles ${registry}/bundle:<version> --tag ${registry}/pixie-oss-pixie-prod-operator-bundle_index:0.0.1 -u docker
docker push ${registry}/pixie-oss-pixie-prod-operator-bundle_index:0.0.1

Deploy Pixie Vizier with the registry flag. You can deploy Pixie Vizier in one of three ways.

Using the CLI:

px deploy --registry <your-registry>

Using Helm:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set registry=<your registry>

Using Yamls:

To deploy Pixie without etcd, use the following yamls:

kubectl apply -f yamls/vizier/vizier_metadata_persist_prod.yaml
kubectl apply -f yamls/vizier_deps/nats_prod.yaml

To deploy Pixie with etcd, use the following yamls:

kubectl apply -f yamls/vizier/vizier_etcd_metadata_prod.yaml
kubectl apply -f yamls/vizier_deps/etcd_prod.yaml

PEM flags are used to configure the Pixie Edge Module, Pixie's data collector component. PEM flags are often used to enable beta features.

For example, to enable STIRLING_ENABLE_AMQP_TRACING when deploying with the Pixie CLI, use the --pem_flags flag:

px deploy --pem_flags="STIRLING_ENABLE_AMQP_TRACING=true"

To enable STIRLING_ENABLE_AMQP_TRACING when deploying with Helm, use the dataCollectorParams.customPEMFlags field:

helm install pixie pixie-operator/pixie-operator-chart --set deployKey=<deploy-key-goes-here> --namespace pl --create-namespace --set dataCollectorParams.customPEMFlags.STIRLING_ENABLE_AMQP_TRACING=true
