What is the problem you are having with rclone?

we have copy job that copy from azure blob storage to gcp gcs bucket.
the way we setup authentication is:
it works fine when i setup storage account level sas token above but I could not find a way to setup container level sas token authentication.

i got 403 issue.
Any idea?

You didn't include the command you are using...

You must include the container name in the rclone command if using container level SAS, so

rclone copy blah azureblob:container

Not

rclone copy blah azureblob:container

Hi,
the command that I used was:
rclone copy src:${CONTAINER}${AZURE_DATA_SUB_PATH}/datafolder dst:${GCS_BUCKET}/destination_folder -v --bwlimit ${BWLIMIT}"M"

Why don't you run rclone with -vv to make a debug log, then we can see exactly what arguments you passed.

That will tell you if there is anything wrong with those env cars.

sure let me get log with --v

Great! That will tell us what

rclone copy src:${CONTAINER}${AZURE_DATA_SUB_PATH}/datafolder dst:${GCS_BUCKET}/destination_folder -v --bwlimit ${BWLIMIT}"M"

Actually arrived as in the first line, eg

2023/11/21 10:47:55 DEBUG : rclone: Version "v1.65.0-beta.7523.15747cc9f.fix-s3-gcs-looping" starting with parameters ["rclone" "lsf" "azureblobsas:rclone" "-vv"]

Also I just verified that the container level SAS URL is working OK for me.

Hi Nick, it turns out the issue was the sas token url is not right.
I've made it work at my end. Thank you for your input.

BTW, we are exploring using azure Service principal (application) to authentication to blob storage.
Is the auth set up can be something like below or differently?

export RCLONE_CONFIG_SRC_ AZURE_TENANT_ID ="tid"
export RCLONE_CONFIG_SRC_ AZURE_CLIENT_ID ="client"
export RCLONE_CONFIG_SRC_CLIENT_SECRET=${secret}

Thanks.

No worries!

You would use these env vars

You can use the azure standard variables also and you would need to set RCLONE_AZUREBLOB_ENV_AUTH=true as well.
