Support for Amazon Linux 2 about quickstart-linux-bastion HOT 5 CLOSED

Hello @knoxilla

To be honest i'm not developing a generic solution for this problem, because i'm not patient enough to add this feature. I copy the existing template and deleted/changed all those sections i don't want to use for amazonlinux2.

I had this problem for so long, so the script under Userdata should be debugged line by line on an EC2 with empty amzlinux2.
As far as i remember the first issue is with the yum can't install the epel-release, because you first have to run some costum command, which the yum install -y epel-release will return.
But I realised that you don't have to install the epel-release, you can simply run yum install -y python2-pip if you want pip2, but you have natively installed pip3 and awscli on amazonlinux2.

So if you want to use amazonlinux2 only, you should rewrite the userdata of the template.
Change all these lines: https://github.com/aws-quickstart/quickstart-linux-bastion/blob/master/templates/linux-bastion.template#L569-L585 to
pip3 install awscli --upgrade

I tweaked the cfn template enough to allow me to deploy the stack using an amzn2 AMI, and things seemed to work OK at first glance. I just did some quick hacks by adding an AMI choice in us-east-1 a la

...
AMZNLINUX2HVM: amzn2-ami-hvm-x86_64-gp2
...
AMZNLINUX2HVM: ami-0b69ea66ff7391e80
...

As I said, it deployed and an instance came up in the ASG and allowed me to connect. Yay!

But the cfn-init failed and bastion.log & CloudWatch logging (among other things, I'm sure) are not happening.

I was hoping I could help push this along but clearly there is more involved beyond my knowledge. I now you are working on v2, and you have my thanks for that!

In case it does help, here is what was logged in /var/log/cloud-init-output.log when things went boom:

Thanks much. I will give it a go - thanks for the pointers and recap of things you'ave already figured out. Cheers,

I am trying to get psql client v10 installed, to connect to a psql 10 RDS instance. It should be wicked easy to get 10 installed on amazon linux 2, and I fear staying on the older version of amazon linux, since support already seems to be dwindling.
