I am testing cloud-init to mount EBS volume to /var/lib/docker in EC2. I
am running coreos-cloudinit manually, but I am not able to mount volume to
local file system.
I have created and attached volume /dev/xvdf in EC2 for my test instance.
My cloud config:
#cloud-config
coreos:
update:
reboot-strategy: "off"
units:
- name: var-lib-docker.mount
enable: true

[Unit]
Description=Mount EBS volume /dev/xvdf to /var/lib/docker
[Mount]
What=/dev/xvdf
Where=/var/lib/docker
Type=ext4
I am running the file as
/usr/bin/coreos-cloudinit --from-file docker.yaml
Result
~ # /usr/bin/coreos-cloudinit --from-file docker.yaml

as you can see the /dev/xvdf is not getting mounted to /var/lib/docker.
Please help with correct cloud-init file or command.
