There’s NO JAVA in docker image

[victorwang123]

Hi, when I Run PEPATAC in a container. The code follows:
docker pull databio/pepatac
But everytime I run the script, it shows : The following required tool(s) are not callable: java python samtools bedtools bowtie2 fastqc macs2 preseq samblaster skewer perl wigToBigWig bigWigCat bedToBigBed Rscript.
And I enter the docker image, I found there's no java. Can you fix this bug? Thanks very much
