Why use fish for kubernetes autocompletion

I am stucking on kubernetes autocompletion on my macbook for a while. Whatever I try with the document (https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion) it does not work

Enable kubernetes automation in fish is the simplest solution

# install fish
$ brew install fish

The problem

The document quality of Google Cloud is far away if compare with AWS. Here is a sample.

If you met below error, when running packer or other SDK,

$ cat packer.json

There are several ways to clone a repository from github. Similar from other providers, such as bitbucket, gitlab, etc.

Mostly, we use

• http
• ssh

Sample clone commands:

Unfortunately as of writing this (Oct 18, 2017) there is no built in integration for multiple target groups per AWS ECS service. Here are a few things you can try:

1. If your application just serves port 80 (HTTP) & port 443 (HTTPS) then you should consider using the application load balancer and terminating SSL at the load balancer. This will allow your application to function using just port 80.

2. If your application serves different ports that are backed by different components, perhaps speaking different protocols then you should consider splitting the application into multiple ECS services. This has the benefit of allowing the different components to independently scale

According to this comment, dynamic variable names are not possible at this time in HCL.

You can use zipmap to emulate this, though it's a bit of a clunky workaround;

locals {
  ec2_tag_keys = ["Name", "Group", "${var.vault_tag_name}"]
 ec2_tag_vals = ["${var.name}", "${var.group_tag}", "${var.vault_tag_value}"]
