问题
I am reading this article which shows me how I can configure my docker VM on top of amazon ec2
https://docs.docker.com/machine/drivers/aws/
I got to the step
docker-machine create --driver amazonec2 aws01
but now I get an error
Error with pre-create check: "unable to find a subnet in the zone: us-east-1a"
I googled and found this thread
https://github.com/docker/machine/issues/1771
but did find anything which worked for me.
Has anyone been able to successfully create a VM on top of AWS using docker-machine?
回答1:
I solved it myself. putting the answer here
first do
aws configure
This will ask you some questions like security id and key. you should be able to get this information from the aws dashboard.
aws ec2 describe-subnets
This will list a bunch of subnet information. Just look at the first one and make note of AvailabilityZone and Subnet Id
docker-machine create --driver amazonec2 --amazonec2-subnet-id=xxxx --amazonec2-zone=c aws01
Here enter the subnet ID you noted from step two and only the last character of the Availability Zone (so if the value is us-east-1c just enter c)
Now you will see
Running pre-create checks...

(aws01) Launching instance...
Waiting for machine to be running, this may take a few minutes...
Detecting operating system of created instance...
Waiting for SSH to be available...

Docker is up and running!
To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env aws01
