Error creating "Ubuntu Bionic ML" instance #102

Closed regzon closed 3 years ago

regzon commented 5 years ago

I am trying to create an instance with the following command (authentication is managed with scaleway-cli):

docker-machine create -d scaleway \
    --scaleway-name "ml-test" \
    --scaleway-image "47d58f71" \
    --scaleway-commercial-type "RENDER-S" \
    ml-test

After some time I receive this error:

Waiting for machine to be running, this may take a few minutes...

err     : exit status 1
output  : root is not in the sudoers file.  This incident will be reported.

Is this is a problem in the driver or in the image and how can I fix it on my side?

To clarify - I've used "Ubuntu Bionic ML 10.1" image

Probably, the problem is that a root user doesn't have sudo permissions because root is not included in /etc/sudoers or /etc/sudoers.d/. Also, the sudo group is not included there for some reason.

Looks like this is a common problem for all "Ubuntu Bionic" images. I've started a regular "Ubuntu Bionic" image on "GP1-XS" and it gave a similar error:

Waiting for machine to be running, this may take a few minutes...
Detecting operating system of created instance...

output  : bash: sudo: command not found

The problem is that docker-machine (in its internals) assumes that the root user can use a sudo command which is not a case in the scaleway "Ubuntu Bionic" and "Ubuntu Bionic ML 10.1" images ("Ubuntu Xenial" works fine). I'll send a ticket to the scaleway about that.

A support team didn't help me, so I've decided to give up on this - I've started using Web UI. For docker-machine, the possible solution is to create a custom image that will provide a sudo permission to the root user.
