Hi,
I am unable to get NFS configured correctly on EC2 instances launched via
the 'ec2' module in Ansible. When I launch instances using the exact same
AMI from the AWS EC2 console, NFS works without a hitch.
First I'll describe my setup, and then how to reproduce the problem. I'm
running Ansible from a Mac OSX Yosemite version 10.10.3.
$ ansible --version
ansible 1.9.2
I was also able to reproduce the problem from a machine running Debian 8.1
with Ansible version 1.9.
This is the ansible playbook I'm using to launch 2 ec2 instances.
$ cat test-nfs.yml
- hosts: localhost
tasks:
- ec2:
key_name: my_key
aws_region: us-east-1
zone: us-east-1c
image: ami-d05e75b8
vpc_subnet_id: subnet-cba9efbc
instance_type: t2.micro
exact_count: 2
count_tag:
Name: nfs-test
instance_tags:
Name: nfs-test
assign_public_ip: yes
wait: yes
Launch two instances.
<command machine>$ ansible-playbook -i ./ec2.py test-nfs.yml
Then, SSH into the first instance and set up NFS.
<command machine>$ ssh ubuntu@<nfs-server ip>
<nfs-server>$ sudo mkdir -m 777 /test
<nfs-server>$ sudo apt-get install nfs-kernel-server
<nfs-server>$ sudo cat "/test *(rw,async,no_subtree_check)" >>
/etc/exports
<nfs-server>$ sudo service nfs-kernel-server restart
Attempt to mount NFS on the second instance.
<nfs-client>$ sudo mkdir -m 777 /test
<nfs-client>$ sudo apt-get install nfs-common
<nfs-client>$ sudo mount <nfs-server ip>:/test /test
The last step (mounting /test) hangs and times out if the instances were
launched using the ansible ec2 module, but completes almost instantly when
the instance are launched from the AWS EC2 console or using the AWS CLI.
$ aws ec2 run-instances --image-id ami-d05e75b8 --count 1
--instance-type t2.micro --key-name test --security-group-ids sg-8fd0f7eb
--subnet-id subnet-cba9efbc
Any help would be greatly appreciated. I can provide additional information
about the setup if requested.
