Running Appscale on Jelastic

问题

Hello we have created a Jelastic Docker environment where we want to run Appscale (https://www.appscale.com/try-appscale) on it:

root@node1234-appscale:~# appscale up
Executing ssh-copy-id for host: 1.8.1.6
root@1.8.1.6's password:
root@1.8.1.6's password:
root@1.8.1.6's password:
root@1.8.1.6's password:

I am wondering why the same password we use to login into the SSH would not work in Docker?

回答1:

Jelastic Gate system is using ssh-keys to connect to the container via ssh. Password-based authentication is disabled for root user inside the container:

sshd_config

# Authentication:

LoginGraceTime 120

PermitRootLogin without-password

StrictModes no

It is a better way and more secure to use key-based authentication than a just password. You can find additional information about Jelastic ssh access in our documentation.

回答2:

AppScale do not uses passwords, but it needs a passwordless setup to get started. So the first time around it tries to copy a freshly generated public key to allow proper functioning. It looks like the setup failed in your case (we do use ssh-copy-id to setup). Try to setup the container so that you can ssh locally (in your case ssh 1.8.1.6) with no need for password, and try to appscale up again.
