Issue

[root@ose2 bwa]# docker run  -v /opt/bwa/data:/data  margin/bwa bwa index /data/Homo_sapiens.GRCh38.dna.chromosome.16.fa
[bwa_idx_build] fail to open file '/data/Homo_sapiens.GRCh38.dna.chromosome.16.fa' : Permission denied

Investigation

https://stackoverflow.com/questions/24288616/permission-denied-on-accessing-host-directory-in-docker

原来是selinux捣的鬼， 在host上运行： chcon -Rt svirt_sandbox_file_t /path/to/volume

解决。

1.容器运行时要求以非root的普通用户运行分析任务

2.可能存储的权限是个问题
