# Running Docker with Swiss Army Knife

Here is the overview of [Swiss Army Knife](https://platform.dnanexus.com/app/swiss-army-knife)

To use an gatk image (made in previous sections) with the Swiss Army Knife tool, you will do the following:

## Command Line

```
dx run app-swiss-army-knife -iimage_file="gatk.tar.gz" -iin="data/mock.vcf" -icmd="gatk SelectVariants -V mock.vcf -O selected.snp.vcf –select-type-to-include "SNP""
```

From there, this will be what the command line prompts will be:

![](/files/9Pq1cAqWwRYn070Lg7OV)

From there, you will see the job log of the Swiss Army Knife App.
