Please run this command with root privileges | CentOS Docker | st2ctl

[RaviTezu]

SUMMARY

Hi, I am trying to run st2 on CentOS docker image and followed the installation steps provided in the docs. After the installation, I am trying to start the services using st2ctl start and it errors out saying "Please run this command with root privileges".

bash-4.2$ id
uid=7447 gid=0(root) groups=0(root),7447
bash-4.2$ st2ctl start
Please run this command with root privileges

I am doing this as part of writing the Dockerfile for installing st2 on CentOS. Unfortunately, I cannot use Ubuntu.

I see that we are checking for uid=0 here and can we skip this check if we are running st2ctl on a container?

Found the issue. Looks the login didn't happen as root. Closing this.

Hi,
I would like to know why we would need root privileges to start the st2 services. Any way that we can allow non-root user to start the services in a container?

st2ctl restart is just a wrapper around service ... commands.
You can check by running service st2api restart in your container from user with no privileges.

Thanks @armab
For security reasons we run the processes as non-root on the container and this check uid==0 is not allowing us to use st2ctl. I have looked at the Dockerfile in st2-devbox and looks like supervisord can help us here.

Take a look also at StackStorm/st2-docker#162 @shusugmt work in progress with supervisord for Xenial images.
Hope that helps.

Thanks for the report.
root privileges are indeed required for restarting a linux service. This comes from OS level and not StackStorm.
Will close this as non issue.
