To organize access to a host for the default CROC system user — ec2-user
, create a key with the ec2-user
name on the Virtual machines → SSH keys page of the CROC console before creating a host. When creating a host, ADCM makes a request to the CROC cloud, and if a key with the ec2-user
name exists, it will copy its public part to the virtual machine settings.
