Process:

1. Only single k8s master running on my laptop, no other node;
2. Install calico as cni;
3. Running sudo edgeadm addon edge-apps --master-public-addr doujohnerk8smaster.com on master;

Result:

To run ls -lad /tmp , its permissions seem be changed:
drwxrw_rwt 3 root root 4096 Feb 14 11:42 /tmp,
which leads to bash: cannot create temp file for here-document: Permission denied if I tried to autocomplete my command.
And I have to manually add umask chmod 1777 /tmp to make it work;

This may be a limitation of your node itself @mhh12121

I have the same issue, and I have tested the permission of /tmp changed after installing superedge with the all in one package

This may be a limitation of your node itself @mhh12121

What would be that limitation, any hints or suggestions ? I'm still confused now:worried:

@mhh12121 It's edgeam's default processing logic: edgeadm uses /tmp as the installation directory, but edgeadm remove the installation directory first and recreate it, that cause the /tmp's permission changing.
You can assign the --worker-path when executing edgeadm init, such as edgeadm init --worker-path /tmp/edgeadm-install, then the /tmp will not affect.

The new edgeadm project https://github.com/superedge/edgeadm has changed the defult WorkPath to /tmp/edgeadm-tmp
