hello.. new flyte user here.. had a question about how can i configure different tasks to use different images in a workflow? i am aware that i can do this by specifying
Copy code
@task(
    container_image="{{.image.img1.fqn }}:{{.image.img1.version}}"
)
and the value of
image.img1.version
can be specified in a config file.. but how is that config linked to tasks while packaging the workflow?

how are you running the packaging flow @Nada Saiyed?
you should be able to pass a config file to your pyflyte run/package/register command.
you should also be able to specify additional images to those commands on the command line as options

pyflyte --pkgs workflows package --image "my-flyte:v1" -f

after registering, run the workflow, and click on the corresponding nodes.
on the right-hand side bar that pops up, click on the task tab. that should bring up the json definition.
the image should be hard-coded there

pyflyte --pkgs workflows --config workflows/my.config package -f
would be enough?

Yee

06/23/2022, 11:51 PM
mind dumping the config here too? (can redact if you need to)

Copy code
[sdk]
workflow_packages=core

[images]
task1 = nsaiyed-flyte:v1
task2 = nsaiyed-flyte:v2
also what is this for?
Copy code
[sdk]
workflow_packages=core

06/23/2022, 11:51 PM
i think you can delete that
yeah that should be fine.
the config should be respected, and the images should get picked up
you’re following the flytesnacks example right?

i get this error
Copy code
containers with unready status: [ajpsqhm6rzqws2tdrcls-n0-0]|Failed to apply default image tag "{{.image.task1.fqn }}:{{.image.task1.version}}": couldn't parse image reference "{{.image.task1.fqn }}:{{.image.task1.version}}": invalid reference format
tried to specify the config file while serializing the workflow as well, but no luck
pyflyte --pkgs workflows serialize --in-container-config-path workflows/my.config workflows -f .

no you shouldn’t need it for the in-container path.
this is weird.
ooh i’m sorry yeah the config file is not respected
😞
we will have to add that, for now you have to use the command line

this syntax
Copy code
pyflyte -c tst.config --pkgs core.flyte_basics package --image a.com/b/c:latest --image task1=nsaiyed-flyte:v1 -f
the first one doesn’t have a name and is the default

is passing a default image name mandatory? i am guessing no
i also tried passing it via command line.. but i keep getting the same error
also if i register using the above command you gave as an example, i am not able to trigger the workflow 😞 i get this error
Request failed with status code 500 failed to create workflow in propeller Unauthorized

hmm. i think so actually - the default bit.
👍 1
at least we typically always include it, so not sure what the behavior is if you don’t. can always use a dummy image
👍 1
the other bit is weird though
should not have a 500
don’t suppose you have access to the cluster and can dump out the admin logs
we should improve that error message.

my cluster is the sandbox cluster.. and killing the container and restarting it seems to have fixed it

Nice
Turn it off and on again.

but still specifying
@task(container_image="{{.image.task2.fqn }}:{{.image.task2.version}}")
throws an error
Copy code
containers with unready status: [axxmntxh2dpm6d742sdp-n0-0]|Failed to apply default image tag "{{.image.task1.fqn }}:{{.image.task1.version}}": couldn't parse image reference "{{.image.task1.fqn }}:{{.image.task1.version}}": invalid reference format
well.. for now i will resort to giving the image name directly since its not able to parse image reference
Copy code
@task(container_image="nsaiyed-flyte:v1")
Thanks a lot for your help

@Marc Paquette @Smriti Satyan @Samhita Alla we should document how to actually link a
flyte.config
file to a flyte workflow when serializing and registering in this page: https://docs.flyte.org/projects/cookbook/en/latest/auto/core/containerization/multi_images.html

@Niels Bantilan, since the image config is not being respected, what would we be using
flyte.config
for?

@Nada Saiyed Hi, in the config file, while providing image name, are you using underscore? Like image_name or something? That might be the issue..

@Smriti Satyan No. example config here
