IUF Error: exec /usr/local/bin/argoexec: argument list too long

Follow this procedure if an IUF step fails with the error: exec /usr/local/bin/argoexec: argument list too long.

  1. Get the name of the template that failed. For example, the s3-upload template failed in the following error.

    2024-03-11T20:40:54.348210Z INFO [cpe-23-12-3-s3-upload          ] BEG s3-upload(0)
2024-03-11T20:40:55.385227Z DBG  [cpe-23-12-3-s3-upload          ]       2024-03-11T20:40:54.569036586Z exec /usr/local/bin/argoexec: argument list too long
2024-03-11T20:41:03.980113Z ERR  [cpe-23-12-3-s3-upload          ] END s3-upload(0) [Failed]

  2. Resolve the error by not echoing{{inputs.parameters.global_params}} in the template. Instead, write {{inputs.parameters.global_params}} to a file and then reference the file.

    1. (ncn-m001#) Navigate to where the workflow templates files are located.

      cd /usr/share/doc/csm/workflows/iuf/operations/

    2. (ncn-m001#) Edit the template where this error occured in the following way.

      1. Search for where echo '{{inputs.parameters.global_params}}' is in the template. The following is an example of how it is used.

        CONTENT=$(echo '{{inputs.parameters.global_params}}' | jq -r '.product_manifest.current_product.manifest')
PARENT_DIR=$(echo '{{inputs.parameters.global_params}}' | jq -r '.stage_params."process-media".current_product.parent_directory')

      2. Before the first line containing echo '{{inputs.parameters.global_params}}', echo global_params to a file.

        echo '{{inputs.parameters.global_params}}' > global.params.data

      3. Replace all instances of echo '{{inputs.parameters.global_params}}' with cat global.params.data.

    3. (ncn-m001#) Save the file and update the argo templates by running the following command.

      /usr/share/doc/csm/workflows/scripts/upload-rebuild-templates.sh

Example of editing a template

If the error happened in the s3-upload step, then edit the /usr/share/doc/csm/workflows/iuf/operations/s3-upload/s3-upload-template.yaml file.

Before making changes, the template will have the following script content.

...
- - name: s3-upload
      templateRef:
        name: iuf-base-template
        template: shell-script
      arguments:
        parameters:
          - name: dryRun
            value: false
          - name: scriptContent
            value: |
              CONTENT=$(echo '{{inputs.parameters.global_params}}' | jq -r '.product_manifest.current_product.manifest')
              PARENT_DIR=$(echo '{{inputs.parameters.global_params}}' | jq -r '.stage_params."process-media".current_product.parent_directory')
              PRODUCT=$(echo '{{inputs.parameters.global_params}}' | jq -r '.product_manifest.current_product.manifest.name')
              VERSION=$(echo '{{inputs.parameters.global_params}}' | jq -r '.product_manifest.current_product.manifest.version')
              ...

After making the changes above, the resulting template should have the following script content.

...
- - name: s3-upload
      templateRef:
        name: iuf-base-template
        template: shell-script
      arguments:
        parameters:
          - name: dryRun
            value: false
          - name: scriptContent
            value: |
              echo '{{inputs.parameters.global_params}}' > global.params.data
              CONTENT=$(cat global.params.data | jq -r '.product_manifest.current_product.manifest')
              PARENT_DIR=$(cat global.params.data | jq -r '.stage_params."process-media".current_product.parent_directory')
              PRODUCT=$(cat global.params.data | jq -r '.product_manifest.current_product.manifest.name')
              VERSION=$(cat global.params.data | jq -r '.product_manifest.current_product.manifest.version')
              ...
