I can have one launchplan create in the production domain, and another create in the staging domain?Glime
02/09/2024, 5:47 PMLaunchPlan.get_or_create()
, you can utilize environment variables to dynamically set the domain during the launch plan creation process. This approach allows you to specify different domains based on your deployment environment, making it possible to have separate launch plans for production and staging.
Here's a conceptual approach based on the information provided in the context:
1. *Use Environment Variables*: Define environment variables in your CI/CD pipeline or local environment to distinguish between production and staging. For example, you could have an environment variable named WORKFLOW_DOMAIN
that can be set to either production
or staging
.
2. *Conditional Launch Plan Creation*: In your Python code where you define the launch plans using LaunchPlan.get_or_create()
, use the WORKFLOW_DOMAIN
environment variable to conditionally set the domain for each launch plan. You can create a conditional logic block that checks the value of WORKFLOW_DOMAIN
and creates the appropriate launch plan for the specified domain.
3. *Register Launch Plans*: When you run pyflyte register
, it will register the launch plans based on the current setting of the WORKFLOW_DOMAIN
environment variable. You can control which domain's launch plan gets registered by setting this environment variable accordingly before running the register command.
Here is a simplified example to illustrate this approach:
import os
from flytekit import LaunchPlan, CronSchedule
from my_workflows import my_workflow
# Check the environment variable to determine the domain
domain = os.getenv("WORKFLOW_DOMAIN")
if domain == "production":
# Create and register the launch plan for production
prod_launch_plan = LaunchPlan.get_or_create(
name="my_workflow_prod_launch_plan",
workflow=my_workflow,
# Additional configurations specific to production
)
elif domain == "staging":
# Create and register the launch plan for staging
staging_launch_plan = LaunchPlan.get_or_create(
name="my_workflow_staging_launch_plan",
workflow=my_workflow,
# Additional configurations specific to staging
)
Before running pyflyte register
, ensure the WORKFLOW_DOMAIN
environment variable is set to the desired domain:
export WORKFLOW_DOMAIN=production # or staging
pyflyte register --pkgs my_package ...
This approach allows you to dynamically create and register launch plans for different domains by simply changing an environment variable.

, .podName
). This method requires that the necessary information (like the wandb project or run ID) is available in the task's configuration or metadata.
Example configuration snippet:
plugins:
logs:
dynamic-log-links-enabled: true
dynamic-log-links:
wandb: <https://wandb.ai/{project}/{run_id}>
In your task definition, you would specify that you want to use this dynamic log link. The specific placeholders ({project}
, {run_id}
) would need to be replaced with the actual path to your wandb project and run ID, which might be dynamically determined based on the task execution.
2. *Using Flyte Decks*: Another approach is to use Flyte Decks to create a more interactive and customized visualization or dashboard that includes your wandb links among other information. This approach is more flexible and allows for a richer presentation of information but requires more development effort. You would use the Flytekit's Deck
and Html
objects to create custom visualizations or dashboards that can be embedded within the Flyte console.
Example code snippet for creating a simple deck with an HTML widget containing a wandb link:
from flytekit import task, workflow
from flytekit.deck import Deck, Html
@task
def my_task() -> str:
# Your task logic here
wandb_run_url = "<https://wandb.ai/{project}/{run_id}>"
deck = Deck(title="My Wandb Run")
deck += Html(f"<a href='{wandb_run_url}'>Wandb Run Link</a>")
deck.flush()
return wandb_run_url
@workflow
def my_workflow():
my_task()
This code creates a deck with a single HTML widget containing a link to a wandb run. The deck.flush()
method sends the deck to the Flyte console where it can be viewed.
Both methods have their use cases. If you simply want to link to external resources like wandb runs, configuring dynamic log links is straightforward and integrates well with the existing Logs section of the Flyte console. If you need more customization or want to present additional information alongside the wandb links, using Flyte Decks provides a powerful way to create rich, interactive dashboards.

In this configuration, {run_id}
would be dynamically replaced with the actual run ID you specify when launching the task. You can customize the URL structure based on your wandb project setup. Step 2: Use Pod Name as wandb Run ID in Your Task To use the pod name as the wandb run ID, your task needs to access the pod name from its environment. Kubernetes injects certain environment variables into pods, but the pod name is not directly available as an environment variable by default. However, you can use the Downward API to expose the pod name as an environment variable. Here's how you can modify a Flyte task to access the pod name and use it as the wandb run ID: from flytekit import task, workflow import os import wandb # Function to initialize wandb def init_wandb(run_id): wandb.init(project="your_project_name", name=run_id) @task def my_task(): # Access the pod name from the environment variable pod_name = os.getenv("POD_NAME") # Initialize wandb with the pod name as the run ID init_wandb(run_id=pod_name) # Your task logic here print("Running task with wandb run ID:", pod_name) @workflow def my_workflow(): my_task() # Modify your Pod spec to include the POD_NAME environment variable using the Downward API pod_spec = { "containers": [ { "name": "mycontainer", "env": [ { "name": "POD_NAME", "valueFrom": { "fieldRef": { "fieldPath": "metadata.name" } } } ] } ] }
In this example, init_wandb
is a function that initializes wandb with a specific run ID. The my_task
function retrieves the pod name from the POD_NAME
environment variable and passes it to init_wandb
as the run ID. You need to ensure that your pod specification includes the POD_NAME
environment variable, which is set using the Downward API to expose the pod's metadata.name (i.e., the pod name). Step 3: Register Your Task and Workflow After defining your task and workflow, and ensuring your Flyte deployment is configured for dynamic log links, you can register your tasks and workflows with Flyte. When executing the task, Flyte will use the configured dynamic log link template, replacing {run_id}
with the pod name, allowing you to access the corresponding wandb run directly from the Flyte console's log links. This approach integrates wandb with Flyte by using dynamic log links and the Kubernetes Downward API, enabling seamless tracking and visualization of your machine learning experiments and their logs.Andrew

, you can increase the logging level of the Flytekit to debug or set specific environment variables to enable more detailed logging. However, based on the provided context, there isn't a direct mention of a built-in flag or command specifically for pyflyte register
to increase verbosity directly related to TypeError exceptions. That said, a general approach to increase verbosity for debugging purposes with Flytekit (the Python SDK for Flyte) involves setting the environment variable FLYTE_SDK_LOGGING_LEVEL
to a more verbose level before running your command. For debugging, you can set it to DEBUG
to get more detailed logs, which might include the stack trace or more context around errors like the TypeError
you're encountering. Here's how you can do it in a Unix-like shell: export FLYTE_SDK_LOGGING_LEVEL=DEBUG pyflyte register ...
This command sets the logging level to DEBUG
(which is more verbose than the default) and then runs the pyflyte register
command. With this setting, Flytekit logs more detailed information about its operations, which could help identify the source of the TypeError
. Additionally, reviewing the Flytekit source code or documentation might provide more insights into enabling verbose error logging or handling specific exceptions like TypeError
more gracefully. If the issue persists, consider reaching out to the Flyte community through their GitHub issues or Discuss forum for more targeted support. Remember, the effectiveness of this approach depends on how Flytekit and your code handle logging. If the error is deep within library code or triggered by specific conditions not logged at the DEBUG level, you might need to investigate further or add custom logging around the suspected source of the error in your code.Andrew
02/12/2024, 8:42 PMdeck = Deck(title="My Wandb Run")
deck += Html(f"<a href='{wandb_run_url}'>Wandb Run Link</a>")
deck.flush()
But the Flyte Deck button never shows up. Is there something other than flush that I need to do to get it to show up, especially if this is the first deck of this task?
I found this in the docs:
flytekit.current_context().default_deck.append(
MarkdownRenderer().to_html(f"[Wandb run link]({link_url})")
)
Does that work if I don’t have a deck yet, or is creating the deck the way to go?Glime
02/12/2024, 8:43 PMdisable_deck=False
in the @task
decorator. This step is crucial because, by default, deck rendering might be disabled to optimize performance. Example: from flytekit import task @task(disable_deck=False) def my_task(): ...
2. Using the Default Deck: If you don't have a deck yet or if it's the first deck of the task, you can use the flytekit.current_context().default_deck
to append your content. This approach works well because every task in Flyte has a default deck associated with it, which can be used to render custom HTML content, including links to external resources like Weights & Biases (wandb). Example: from flytekit import current_context from flytekit.deck.renderer import MarkdownRenderer link_url = "<https://wandb.ai/your_project/your_run>" current_context().default_deck.append( MarkdownRenderer().to_html(f"[Wandb run link]({link_url})") )
3. Creating and Flushing a New Deck: If you prefer to create a new deck (for example, to group certain types of information together), you can instantiate a Deck
object, add content to it, and ensure it's appended to the Flyte context's decks. The flush()
method you mentioned is used to send the deck to the Flyte console, but it's crucial that the deck is also recognized by the Flyte context. Example: from flytekit import Deck, Html, current_context deck = Deck(title="My Wandb Run") wandb_run_url = "<https://wandb.ai/your_project/your_run>" deck += Html(f"<a href='{wandb_run_url}'>Wandb Run Link</a>") # Append the new deck to the current context's decks current_context().user_space_params.decks.append(deck)
4. Check for Any Additional Configuration Requirements: Depending on your Flyte deployment or the specific version of Flytekit you're using, there might be additional steps or configurations required to enable deck rendering. It's a good idea to consult the Flyte documentation or the Flyte community for any recent updates or tips. In summary, if it's the first deck of the task or you don't have a deck yet, using flytekit.current_context().default_deck
is a straightforward way to go. Ensure that deck rendering is enabled for your task, and consider creating a new deck if you need to group specific types of information together.

02/12/2024, 10:53 PMFLYTE_CREDENTIALS_CLIENT_ID
and FLYTE_CREDENTIALS_CLIENT_SECRET
leading to a 401
error, it's crucial to ensure that the client ID and client secret are correctly configured and recognized by Flyte. The error you're encountering indicates a problem with client authentication, which could be due to incorrect credentials or misconfiguration. Here are steps to troubleshoot and resolve the authentication issue: 1. Verify Credentials: Ensure that the FLYTE_CREDENTIALS_CLIENT_ID
and FLYTE_CREDENTIALS_CLIENT_SECRET
you are using are correct and have been obtained from your identity provider (IdP). These credentials must match what's registered in your Flyte deployment for the CI/CD system. 2. Use Environment Variable Redirection: If your CI system does not allow setting custom environment variables directly, you can use environment variable redirection. For example, if your CI system sets the client secret under a different variable name, you can redirect it as follows: export FLYTE_CREDENTIALS_CLIENT_SECRET_FROM_ENV_VAR=OTHER_ENV_VARIABLE
This tells Flyte to look for the client secret in OTHER_ENV_VARIABLE
instead of FLYTE_CREDENTIALS_CLIENT_SECRET
. 3. File-Based Secret Configuration: If your CI system supports mounting secrets as files, you can use the FLYTE_CREDENTIALS_CLIENT_SECRET_FROM_FILE
environment variable to specify the path to the file containing the client secret: export FLYTE_CREDENTIALS_CLIENT_SECRET_FROM_FILE=/path/to/client/secret/file
4. Check for Misconfiguration in Helm Chart or Flyte Deployment: If you're deploying Flyte using Helm, ensure that the client ID and secret are correctly configured in your Helm values or directly in your Kubernetes secrets. Misconfiguration here could lead to the invalid_client
error. 5. Review Flyte and Flytectl Configuration: Ensure that your flyteadmin
configuration (for Flyte) and config.yaml
(for Flytectl) are correctly set up for client credentials flow. This includes setting the correct authType
and ensuring that the endpoint and client credentials are correctly specified. 6. Consult Flyte Documentation and Community: Review the Flyte authentication setup documentation for more details on configuring authentication, especially in CI/CD environments. If the issue persists, consider reaching out to the Flyte community on GitHub or Discuss for more specific guidance. Given the error message you're seeing, the issue likely lies in how the client ID and secret are being passed or recognized by Flyte. Double-checking these configurations against the documentation and ensuring that your CI system is correctly passing these values should help resolve the authentication issue.
