Gurus,

I’m trying to create a docker image from a Dockerfile in an ec2 instance. I’m able to create the ec2 instances and copy over the dockerfile fine. However, for _every_ ec2 instance I fire up, it _always_ fails the first time I try to build the docker image.

- name: Build the docker Nginx image  
docker\_image:  
path: “{{ docker\_nginx\_dir }}”  
state: build  
name: “grid/nginx”

The ansible failure stack trace looks like:  
failed: [54._XX.XX.XX_] =\> {“failed”: true, “parsed”: false}  
invalid output was: SUDO-SUCCESS-bdbbnpaupjsbudcxajoycrwmbmlehwux

Looking at the docker log file on the ec2 instance, the only obvious error I always see is something like:

[f648bc68] -job log(start, aab655401a74e9e6bb098c1d62d31e44beb1c116eb530296f315392a82c2e3dc, 4d76087678ee) = OK (0)  
**[error] attach.go:186 attach: stdout: write unix @: broken pipe**  
[error] attach.go:258 attach: job 1 returned error write unix @: broken pipe, aborting all jobs  
write unix @: broken pipe  
[f648bc68] -job build() = ERR (1)

I subsequently bumped up the timeout value thinking that the ssh client was timing out:

- name: Build the docker Nginx image  
docker\_image:  
**timeout: 1200**  
path: “{{ docker\_nginx\_dir }}”  
state: build  
name: “grid/nginx”

But it fails much before this timeout. So I added a retry condition:

- name: Build the docker Nginx image  
docker\_image:  
timeout: 1200  
path: “{{ docker\_nginx\_dir }}”  
state: build  
name: “grid/nginx”  
**register: build\_image\_result**  
**until: not build\_image\_result|failed**  
**retries: 2**  
**delay: 30**

This seems to consistently work - and I see that it always gets called twice - but I’m concerned as to why it would always need to. Any ideas?

Thanks!

More info if anyone needs it:  
**EC2 setup**

- name: Setup AWS EC2 Instances - US-West-1  
ec2:  
instance\_type: t2.micro  
image: “ami-41a7ea71”  
monitoring: no  
wait: yes  
group: microserver\_security\_group  
key\_name: _mykey_  
instance\_tags:  
Name: “MicroServer”  
count: 1  
region: “us-west-2”  
register: ec2west2

Docker install tasks:

- name: Update packages on the Amazon AMI  
yum: name=\* state=latest  
when: ansible\_distribution == ‘Amazon’

- name: Install or Update Python on the Amazon AMI  
yum: name=python state=latest  
when: ansible\_distribution == ‘Amazon’

- name: Install or Update Python-pip on the Amazon AMI  
yum: name=python-pip state=latest  
when: ansible\_distribution == ‘Amazon’

- name: Install or Update Docker on the Amazon AMI  
yum: name=docker state=latest  
when: ansible\_distribution == ‘Amazon’

- name: Install or Update docker-py on all docker hosts  
pip: name=docker-py version=0.3.1

# Had to delete /tmp/pip-build-root because pip would keep installing docker-py 0.5.3 as it was cached in this directory

- name: Start the docker service on the Amazon AMI  
service: name=docker state=restarted

# Trying restarted because it always seems to fail the first time around

when: ansible\_distribution == ‘Amazon’

Cheers.

Can you share the versions of Ansible, docker, and docker libraries you are using for starters?

Please check on the latest version of Ansible – preferably the development branch since this is Docker and changing extremely quickly - and let us know if you still encounter problems.
