@ancient-wolf-19325 Can I automatically configure image registry secret to be used by service account created by the flyte-core Helm chart?
a
Yes, you can automatically configure an image registry secret to be used by a service account created by the 
flyte-core
Helm chart. This involves creating a Kubernetes secret with your registry credentials and then configuring the 
imagePullSecrets
in the Helm chart's 
values.yaml
file. 1. Create a Kubernetes Secret: First, create a Kubernetes secret that contains your registry credentials. This can be done using the 
kubectl
command:
Copy code
kubectl create secret docker-registry my-registry-secret \
      --docker-server=<your-registry-server> \
      --docker-username=<your-username> \
      --docker-password=<your-password> \
      --docker-email=<your-email>
2. Configure 
imagePullSecrets
in 
values.yaml
: Update the 
values.yaml
file of the 
flyte-core
Helm chart to include the 
imagePullSecrets
configuration for the service account. For example:
Copy code
flyteadmin:
      serviceAccount:
        create: true
        name: flyteadmin
        imagePullSecrets:
          - name: my-registry-secret
3. Deploy the Helm Chart: Apply the updated Helm chart to your Kubernetes cluster:
Copy code
helm upgrade --install flyte-core flyteorg/flyte-core -f values.yaml
This configuration ensures that the service account used by Flyte will have access to the private image registry. Would you like more detailed steps or code snippets for these configurations?

@ancient-wolf-19325 is the above possible if Flyte manages namespaces for project? The secret would need to exist before the service account is created, but since Flyte also creates the namespace, there is no chance for the secret to be there.
a
When Flyte manages namespaces for projects, it indeed creates separate namespaces for each project, which complicates the pre-existence of secrets. However, you can use a custom pod template to ensure that the 
imagePullSecrets
are included in every pod created by Flyte, regardless of the namespace. 1. Create a Kubernetes Secret: Create the secret in the namespace where Flyte is deployed:
Copy code
kubectl create secret docker-registry my-registry-secret \
      --docker-server=<your-registry-server> \
      --docker-username=<your-username> \
      --docker-password=<your-password> \
      --docker-email=<your-email> \
      --namespace=<flyte-namespace>
2. Configure Custom Pod Template: Use a custom pod template to include the 
imagePullSecrets
. Update the FlytePropeller configuration to use this custom pod template. Here is an example of how to define a custom pod template:
Copy code
apiVersion: v1
    kind: Pod
    metadata:
      name: custom-pod-template
    spec:
      imagePullSecrets:
        - name: my-registry-secret
3. Update FlytePropeller Configuration: Update the FlytePropeller configuration to use the custom pod template. This can be done by modifying the FlytePropeller configuration in the Helm chart's 
values.yaml
file:
Copy code
propeller:
      config:
        default:
          podTemplatePath: /path/to/custom-pod-template.yaml
4. Deploy the Helm Chart: Apply the updated Helm chart to your Kubernetes cluster:
Copy code
helm upgrade --install flyte-core flyteorg/flyte-core -f values.yaml
This approach ensures that the 
imagePullSecrets
are included in every pod created by Flyte, regardless of the namespace. Would you like more detailed steps or code snippets for these configurations? Sources: - Private Images Documentation - Custom Pod Template Example 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 how can I configure Flyte deployed using flyte-core Helm chart to use preconfigured namespace?
a
To configure Flyte to use a preconfigured namespace when deploying with the 
flyte-core
Helm chart, you need to adjust the namespace mapping in the FlyteAdmin configuration. This will ensure that Flyte uses the specified namespace instead of creating new ones for each project-domain combination. Here are the steps to achieve this: 1. Update 
values.yaml
: Modify the 
values.yaml
file of the 
flyte-core
Helm chart to include the namespace mapping configuration. You can set the 
namespace_mapping
template to use a preconfigured namespace.
Copy code
flyteadmin:
      config:
        namespaceMapping:
          template: "my-preconfigured-namespace"
2. Deploy the Helm Chart: Apply the updated Helm chart to your Kubernetes cluster:
Copy code
helm upgrade --install flyte-core flyteorg/flyte-core -f values.yaml
This configuration ensures that Flyte uses the specified namespace (
my-preconfigured-namespace
) for all project-domain combinations. Would you like more detailed steps or code snippets for these configurations? Sources: - Flyte Namespace Configuration - Flyte Helm Chart Values 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 what is the meaning of 
template
key? Is this literally the namespace's name?
a
The 
template
key in the FlyteAdmin configuration for namespace mapping is a template string that defines how namespaces should be named based on the project and domain. It uses placeholders like 
{{ project }}
and 
{{ domain }}
to dynamically generate namespace names. For example, if you set the 
template
to 
"{{ project }}-{{ domain }}"
, Flyte will create namespaces like 
myproject-development
or 
myproject-production
based on the project and domain values. If you want to use a preconfigured namespace, you can set the 
template
to a fixed string, which will be used as the namespace name for all projects and domains. For instance, setting 
template
to 
"my-preconfigured-namespace"
will make Flyte use 
my-preconfigured-namespace
for all workflows, regardless of the project or domain. Here is an example configuration in the 
values.yaml
file:
Copy code
flyteadmin:
  config:
    namespaceMapping:
      template: "my-preconfigured-namespace"
This configuration ensures that Flyte uses the namespace 
my-preconfigured-namespace
for all project-domain combinations. Would you like more detailed steps or code snippets for these configurations? Sources: - Flyte Namespace Configuration - Flyte Helm Chart Values 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 in such configuration, how can I control which service account is used to execute user workloads?
a
To control which service account is used to execute user workloads in a Flyte deployment using a preconfigured namespace, you can specify the service account in the FlyteAdmin configuration. This can be done by setting the 
serviceAccount
field in the 
values.yaml
file of the 
flyte-core
Helm chart. Here are the steps to configure the service account: 1. Update 
values.yaml
: Modify the 
values.yaml
file to include the service account configuration. You can specify the service account name that should be used for executing user workloads.
Copy code
flyteadmin:
      config:
        namespaceMapping:
          template: "my-preconfigured-namespace"
        securityContext:
          runAs:
            k8sServiceAccount: "my-service-account"
2. Deploy the Helm Chart: Apply the updated Helm chart to your Kubernetes cluster:
Copy code
helm upgrade --install flyte-core flyteorg/flyte-core -f values.yaml
This configuration ensures that Flyte uses the specified service account (
my-service-account
) for executing user workloads in the preconfigured namespace (
my-preconfigured-namespace
). Would you like more detailed steps or code snippets for these configurations? Sources: - Flyte Namespace Configuration - Flyte Helm Chart Values - Flyte Security Context 👍 0 button 👎 1 button 💡 Hint: Mention @ancient-wolf-19325 in the thread for followups.

@some-solstice-93243 by default the wf execution will use the 
default
Service Account on the corresponding `project-domain`namespace. You can either configure the execution to use something different imperatively (say 
pyflyte run --service-account ...
or configure it platform-wide. For the latter, consider using the Cluster Resource Manager (example)
what RunLLM mentioned in the previous answer applies for the 
flyteadmin
Pod, not the executions
s
@average-finland-92144 thanks so much! I will have to look into enabling cluster resource manager - never used it. Currently building a poc, and trying to find as simple solution as possible 🙂.
👍🏽 1
@average-finland-92144 one more question, should using namespace tempalte with cluster resource manager prevent Flyte from creating new namespaces for each project?
a
nop, it's the opposite, it instructs Flyte on how to create those namespaces. You can use the namespace_mapping feature to isolate executions to a specific namespace
s
the way RunLLM initially suggested?
a
yep
