You have to set “secondary okay” mode to let the mongo shell know that you’re allowing reads from a secondary. This is to protect you and your applications from performing eventually consistent reads by accident. You can do this in the shell with: rs.secondaryOk() After that you can query normally from secondaries. A note about … Read more

Examples: $ aws configure –profile account1 $ aws configure –profile account2 You can then switch between the accounts by … Read more

Your question Is ECS just a docker install in EC2? If I already have a EC2, then I start a ECS, does it mean I have two instance? No. AWS ECS is just a logical grouping (cluster) of EC2 instances, and all the EC2 instances part of an ECS act as Docker host i.e. ECS … Read more
I’ve chmoded my keypair to 600 in order to get into my personal instance last night, And this is the way it is supposed to be. From the EC2 documentation we have “If you’re using OpenSSH (or any reasonably paranoid SSH client) then you’ll probably need to set the permissions of this file so that … Read more

Jaminto did a great job of answering the question, but I recently went through the process myself and wanted to expand on Jaminto’s answer. I’m assuming that you already have an EC2 instance created and have associated an Elastic IP Address to it. Step #1: Install vsftpd SSH to your EC2 server. Type: > sudo … Read more
You can’t apply a keypair to a running instance. You can only use the new keypair to launch a new instance. For recovery, if it’s an EBS boot AMI, you can stop it, make a snapshot of the volume. Create a new volume based on it. And be able to use it back to start … Read more
No. You get charged for: Online time Storage space (assumably you store the image on S3 [EBS]) Elastic IP addresses Bandwidth So… if you stop the EC2 instance you will only have to pay for the storage of the image on S3 (assuming you store an image ofcourse) and any IP addresses you’ve reserved.
Basically, root volume (your entire virtual system disk) is ephemeral, but only if you choose to create AMI backed by Amazon EC2 instance store. If you choose to create AMI backed by EBS then your root volume is backed by EBS and everything you have on your root volume will be saved between reboots. If … Read more
