The DockerCon16 Recap presentation i performed during DevOps Turkey Meetup link is here.
Whenever you need to enable the HTTPS secure communication for your website, if your are using AWS, ELB is a cool service on which you can define your SSL certificate and termination and scale the nodes without considering the certificate. ELB is able to perform SSL termination and communicate with the nodes with HTTP.
First of all you need to create a CSR (Certificate Signing Request), assuming you need Wildcard SSL, CN is *.domain.com :
openssl req -new -newkey rsa:2048 -nodes -out star_domain_com.csr -keyout star_domain_com_private.key -subj "/C=TR/ST=Istanbul/L=Istanbul/O=domain/OU=IT/CN=*.domain.com"
There will be 2 output files:
1. star_domain_com_private.key : This will be your private key
2. star_domain_com.csr : This will be used to request the certificate from a Certificate Authority
Next step is, by the help of CSR, to initiate the SSL certificate request from a certificate authority of your choice.
You will be provided from Certificate Authority, a Public Key:
AWS is expecting from you a PEM format. In order to achieve that, you need to convert your certificate from CRT to PEM using openssl:
openssl x509 -in d06409309fccd3b.crt -out domain_public.pem -outform PEM
For the private key you already created, which is RSA, you also need to convert it to PEM:
openssl rsa -in star_domain_com_private.key -text > domain_private.pem
The next phase is uploading the public and private key to AWS in PEM format:
AWS –> EC2 –> Load Balancers
Create or open a current Load Balancer –> Listeners –> Add –> HTTPS –> Change –> Upload a new SSL Certificate
Copy and paste the public and private keys into the fields and Save
This is the most weird incident i ever experienced concerning with OS/HW !
After my Macbook comes back from the sleep mode, the USB keyboard stopped reacting, seems the USB port even stopped providing 5V electricity.
What i did:
1- Plugged the keyboard to another USB port, it works!! So no problem with the keyboard
2- Plugged other USB devices to the problematic USB port, it works!! So no problem with the USB port
I also reset PRAM and SMC, but still this did not bring any difference.
After, i found out the following thead under Apple discussions:
Seems i am not the one who is having that experience, that's good at least!:)
The solution is:
– Connect any USB extension cable between the keyboard and the USB port, and it works:
This is the most weird situation EVER!!
The question is: How long will i need to keep on using the USB extension, forever?
Sometimes this may be required, here is the practical way to do that:
useradd -s /bin/bash -m -d /home/YOURUSER -g root YOURUSER
USERNAME ALL=(ALL:ALL) ALL
