Dockerized single-node ECS in AWS

[Anonymous]

I tried get a single node ECS running in AWS.

I launched a CentOS 7 instance and cloned the ECS repository from Github.

Unfortunately the step1_ecs_singlenode:install Python script failed with the following error message:

The command I executed looks like:

The /etc/ hosts and /etc/sysconfig/network on my CentOS instance looks like

Any idea what I've to change to get my container configured and running?

Thanks

Hello Undine,

The issue is the hostname. What is the result when you run command  hostname and hostname -i ?

i will recommend to update hostname to be ecs-single-node. update hosts file to reflect the new hostname and pass ecs-single-node as parameter value.

Thanks fir the hint. My first problem is solved.

The single node docker image is running on my CentOS EC2 instance.

I assume you could help me for my next problem as well.

What exactly do I have to do to get my ECS GUI started?

Could I connect from a web browser running on my MAC to the dockerized ECS running on EC2?

Thanks

Best regards

Undine

Hello Undine,

To access ECS GUI you need to know the AWS instance public IP address. Make sure port 443 is open then from your Mac machine go to https://<AWS Public IP Address>

Hi Magdy,

thanks, it helped, I finally got connect to the GUI.

Sorry for this stupid question ... I totally ignored the public IP, these are my first steps with docker and EC2

Unfortunately I've the next question now.

I am running in the following error running the step2_object_provisioning.

I still could dial-in to the GUI, the ova1 is there. But the status tays partially ready for ever.

Do you have any idea what I could do?

Thanks

Undine

Hello Undine,

We have challenge with step 2. I know our Engineering team is looking into it. You can use GUI steps section to finalize ECS preparation.
