Is it supported to submit jobs to volcano using WDL language in Cromwell？

[chloe6888]

The community provides the configuration of using volcano as the cromwell backend, but when the job is submitted, it cannot be successfully delivered to the volcano.

Environment:

• OS：Centos 7.9
• Runtime: Containerd
• Kubernetes version: 1.24.2
• Volcano version: 1.6.0

## https://cromwell.readthedocs.io/en/develop/backends/Volcano/
backend{
  default = Volcano
  providers{
    Volcano {
      actor-factory = "cromwell.backend.impl.sfs.config.ConfigBackendLifecycleActorFactory"
      config {
        runtime-attributes = """
        Int runtime_minutes = 600
        Int cpus = 2
        Int requested_memory_mb_per_core = 8000
        String queue = "short"
        """
        submit = """
            kubectl apply -f ${script}
        """
        kill = "vcctl job delete -N ${job_id}"
        check-alive = "vcctl job view -N ${job_id}"
        job-id-regex = "(\\d+)"
      }
    }
  }
}

test example:

## hw.wdl
task bwa_mem_tool {
  String reads_fq1 = "SRR1976948_1.fastq.gz"
  String reads_fq2 = "SRR1976948_2.fastq.gz"
  String outputdir = "/ags-wdl/bwatest/output"
  String fastqFolder = "fastqfolder"
  command {
        mkdir -p /bwa/${fastqFolder}
        cd /bwa/${fastqFolder}
        rm -rf SRR1976948*
        wget https://ags-public.oss-cn-beijing.aliyuncs.com/alignment/subset_assembly.fa.gz
        wget https://ags-public.oss-cn-beijing.aliyuncs.com/alignment/SRR1976948_1.fastq.gz
        wget https://ags-public.oss-cn-beijing.aliyuncs.com/alignment/SRR1976948_2.fastq.gz
        gzip -cd ${reference} > subset_assembly.fa
        gunzip -c ${reads_fq1} | head -800000 > SRR1976948.1
        gunzip -c ${reads_fq2} | head -800000 > SRR1976948.2
        bwa index subset_assembly.fa
        bwa aln subset_assembly.fa SRR1976948.1 > ${outputdir}/SRR1976948.1.untrimmed.sai
        bwa aln subset_assembly.fa SRR1976948.2 > ${outputdir}/SRR1976948.2.untrimmed.sai
  }
  output {
    File sam1 = "${outputdir}/SRR1976948.1.untrimmed.sai"
    File sam2 = "${outputdir}/SRR1976948.2.untrimmed.sai"
  }
  runtime {
    docker: "biocontainers/bwa:v0.7.17_cv1"
    memory: "2GB"
    cpu: 1
  }
}
workflow wf {
  call bwa_mem_tool
}

What I want to know:

Is it supported to submit jobs to volcano using WDL language in Cromwell？If supported, can you provide relevant cases for users？If not, when will it be supported in the future？
