JFrog Xray安装在CentOS上进行Docker安装-权限被拒绝

Question

Trying to install JFrog Xray on a CentOS machine, using the Docker installer. I've created a /opt/xray directory, where I've downloaded the install file into.

Then ran chmod +x xray on this file.

When I try to install using sudo "./xray install", I get the following output:

[root@xray xray]# sudo ./xray install
INFO: Using XRAY_MOUNT_ROOT=/root/.jfrog/xray
Verifying Xray prerequisites ...

./wrapper.sh: line 589: /data/installer.info: Permission denied

Any ideas what may be causing this?

I had a similar issue on RHEL and it was selinux getting in the way. To fix it, change the following line in the xray script: -

XRAY_VOLUMES="-v ${XRAY_MOUNT_ROOT}/xray-installer:/data -v ${XRAY_MOUNT_ROOT}:/xray_global_mount_root"

To this: -

XRAY_VOLUMES="-v ${XRAY_MOUNT_ROOT}/xray-installer:/data:z -v ${XRAY_MOUNT_ROOT}:/xray_global_mount_root:z"

(basically adding :z to each volume).

This makes sure the folder is labelled to be used by multiple containers in selinux.
