UidGidResolver

The UidGidResolver resolves user ids and group ids to their corresponding names.

This is done by reading /etc/passwd and /etc/group on the host. Therefore any UID inside a container might not properly match the username inside the container. Since the path is hardcoded usernames provided through ldap, nss-systemd, systemd units with DynamicUser=yes, ... will not be resolved correctly.

Usage​

Classic gadgets​

  1. Implement the UidResolverInterface for the event struct to resolve a UID. The UID which is returned by GetUid() will be resolved to the corresponding username and is passed into SetUserName(...) 
    type UidResolverInterface interface {
      GetUid() uint32
      SetUserName(string)
    }
  2. Implement the GidResolverInterface for the event struct to a resolve GID. The GID which is returned by GetGid() will be resolved to the corresponding groupname and is passed into SetGroupName(...) 
    type GidResolverInterface interface {
      GetGid() uint32
      SetGroupName(string)
    }
