Can anyone help me with the pricing and support for Subdomain for Google-managed SSL certificate in Load Balancing.
I am working with https for Static website.
https://medium.com/#marco_37432/create-a-custom-domain-cdn-with-google-beta-7ad9531dfbae
I want to create a Subdomain with admin.example.com to link Google-managed SSL certificate in Load Balancing
But with Google docs I can see "Its not supporting wildcard common names or multiple subject alternate names" I cant understand, Can any one explain me and can I use create admin.example.com to link Google-managed SSL certificate.
With pricing I can see its free in https://geekflare.com/google-managed-certificate-lb/ Can I find them google Document to confirm.
Google Cloud Managed SSL Certificates are free.
You can only use Google Managed SSL Certificates with Google services such as load balancers. You cannot use them on services you control. Google does not make the certificate private key available.
Google services such as load balancers support more than one SSL certificate. Each Google managed certificate can only have one verified domain name. This can be a subdomain of a root domain you own/control. Wildcards are not supported.
If any of the above limitations affect you, then you will need to select self-managed certificates. You can easily create your own Let's Encrypt SSL certificates with Cloud Shell.
Example commands to run on Cloud Shell:
wget https://dl.eff.org/certbot-auto
chmod +x certbot-auto
./certbot-auto certonly --manual --preferred-challenges dns -d 'example.com' -d '*.example.com'
I wrote an article that covers this in detail here.
As of today (2020-01-28) Google supports multiple domains in a single certificate (in beta):

I am a bit new to Google Compute engine and managed to get a webserver with nginx to work on my google domain and installed WordPress. HTTP access was working. Now I wanted to get HTTPS to work as well.
I noticed that I don't have SSL running and so I ended up using cloudflare, made necessary changes to my nginx server and also changed the nameserver for my webserver IP address on the Google Compute Engine. That works fine. Although, there are still some errors when accessing the IP address instead of the domain name (400 Bad Request No required SSL certificate was sent nginx/1.18.0 (Ubuntu)).
So, I heard Google can do SSL on my google domain, but I am really stuck with the documentation, https://cloud.google.com/appengine/docs/standard/python/securing-custom-domains-with-ssl?authuser=2#upgrading_to_managed_ssl_certificates. It talks about Google App Engine and I haven't found a documentation to apply SSL certificates to my Google Compute Engine instance. Though, I added a custom domain there, but it points to a different IP address than my webserver on the Google Compute Engine. That surely can't be the right way?
Hence, does anyone know how I can get SSL from Google to work on my webserver using a VM instance on Google Compute Engine?
(Note to myself: https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04)
It is very easy to set up SSL on Compute Engine.
STEP 1: Domain names
Determine which domain names you want SSL certificates for. Typically you want two. The naked domain (example.com) and the zone www (www.example.com). Replace example.com with your actual domain name.
Note: Let's Encrypt will not issue SSL certificates for an IP address. This also means you cannot access your web server using SSL specifying an IP address instead of a domain name. Trying this will generate an error: https://my-ip-address.com
STEP 2: Setup DNS
Change your DNS servers to point directly to your Compute Engine instance reserved static IP address. At this point, do not use CloudFlare. Let's Encrypt will talk directly to your Nginx web server. Validate that each domain name is configured correctly and that you can access your site via HTTP (http://example.com and http://www.example.com).
The following instructions are OS dependant and are for Debian based systems such as Debian and Ubuntu. There are similar steps for CentOS, Red Hat, etc.
STEP 3: Install Certbot
Certbot is the software agent for Let's Encrypt. This requires Python3 to be installed on your system. Most Google Cloud instances have Python 3 installed.
Run the following commands on your VM instance:
sudo apt update
sudo apt upgrade -y
sudo apt install certbot python3-certbot-nginx
STEP 4: VPC Firewall
Make sure that ports 80 and 443 are allowed in the Google Cloud VPC Firewall.
Using firewall rules
STEP 5: Issue the SSL Certificate
Run the following command on your VM instance. Replace example.com with your domain names.
sudo certbot --nginx -d example.com -d www.example.com
Summary
Your server now has SSL configured. The SSL certificate will auto-renew. Provided that you do not change the domain names or DNS server settings, SSL will continuously function.
In the future, you may decide to offload SSL certificates to another service such as Cloudflare or a Google HTTP(S) Load Balancer. I recommend understanding how to set up SSL directly on your instance so that encryption is end-to-end. Then you can decide on SSL-offloading, caching, load balancing, auto-scaling, and more options.
I am struggling to get SSL to work on an elastic beanstalk environment with the following configuration:
I have the domain hosted with GoDaddy, which I have routing through cloudflare, which then routes to Route53 with an A record pointing to my subdomain api.myapp.com (which points to my EB environment).
I am using Cloudflare's full E2E encryption, and am using the SSL certificate provided by cloudflare.
In my EB environment, I am using a Classic Load Balancer and have the following configuration (note: my application uses websockets hence the TCP port):
I've added the SSL certificate to the HTTPS configuration but when I navigate to api.myapp.com I am still getting the "your connection is not secure" in the browser.
Does anyone have any suggestions on how to resolve the issue?
The free ssl from zerossl.com works. After the validation and others stuffs at the end you will get three files.
Using AWS Console
Download the zip files containing certificate, chain and private. Goto AWS certificate manager -> import certificate -> add all the details -> review and import the certificate.
Using AWS CLI, which will output the certificate identifier
aws iam upload-server-certificate --server-certificate-name ish --certificate-body file://certificate.crt --certificate-chain file://ca_bundle.crt --private-key file://private.key
Goto AWS Console load balancer and select 443 HTTPs the recent certificate will be available which can be identified by an identifier provided on both the above cases. Apply changes and restart the env. The new certificate will be available.
Turns out that AWS doesn't allow the use of SSL certificates purchased from cloudflare anymore, so I solved it by provisioning one with CA on AWS.
We have 10 different kubernetes pods which runs inside a private VPN, this pods are HTTP serving endpoints(not HTTPS). But this services would interact with HTTPS serving endpoints. Logically to make call to HTTP-S serving endpoints from a HTTP serving pod , the SSL server certificate trust is required. Hence we decided to store the SSL certificates inside each HTTP Service pods to make call to HTTPS serving pods.
I am wondering is there are any alternative approaches for managing SSL certificates across different pods in Kubernetes cluster? How about kubeadm for K8s certificate management ... any suggestions ?
This is more of a general SSL certificate question rather than specific to Kubernetes.
If the containers/pods providing the HTTPS endpoint already have their SSL correctly configured and the SSL certificate you are using was purchased/generated from a known, trusted CA (like letsencrypt or any one of the known, trusted certificate companies out there) then there is no reason your other container apps that are making connections to your HTTPS endpoint serving pods would need anything special stored in them.
The only exception to this is if you have your own private CA and you've generated certificates on that internally and are installing them in your HTTPS serving containers. (Or if you are generating self-signed certs). Your pods/containers connecting to the https endpoints would then need to know about the CA certificate. Here is a stackoverflow question/answer that deals with this scenario:
How do I add a CA root certificate inside a docker image?
Lastly, there are better patterns to manage SSL in containers and container schedulers like Kubernetes. It all depends on your design/architecture.
Some general ideas:
Terminate SSL at a load balancer before traffic hits your pods. The load balancer then handles the traffic from itself to the pods as HTTP, and your clients terminate SSL at the Load Balancer. (This doesn't really tackle your specific use case though)
Use something like Hashicorp Vault as an internal CA, and use automation around this product and Kubernetes to manage certificates automatically.
Use something like cert-manager by jetstack to manage SSL in your kubernetes environment automatically. It can connect to a multitude of 'providers' such as letsencrypt for free SSL. https://github.com/jetstack/cert-manager
Hope that helps.
I'm trying to have https for a website which is hosted in AWS EC2. I have followed the steps mention in the following link.
https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-14-04
But still its showing the privacy thing to all user who are visiting the website. How can make the certificate as trusted or how long it will take Amazon to make it a trusted one.
Please help me to solve this. I'm stuck with this for last 2 days. Answers will be appreciated and Thank you.
You can use AWS Certificate Manager to issue free SSL certificate signed by AWS Certificate Authority. However for this to work, you need to use a Load Balancer and attach the certificate to the Load Balancer which will forward the traffic to the EC2 instance.
Depending on your requirements you may wish to use SSL termination on an Elastic Load Balancer (ELB) instead.
This involves creating a free AWS certificate and an ELB. Attach both your instance the certificate to the ELB with HTTPS forwarded to port 80 on your instance.
Then just point your DNS name to the ELB. If you're using Route53 then you can just use an A-record alias.
Edit: If you want to automatically direct HTTP to HTTPS you'll need to check the X-Forwarded-Proto header in Apache's .htaccess file. More information here.
The certificate which you are using is a "Self Signed Certificate (https://en.wikipedia.org/wiki/Self-signed_certificate)".
In order to get rid of insecure certificate or privacy issues on HTTPS, you need to get your CSR signed from a trusted CA like Comodo, Godaddy etc.

OR
In case you want free verified SSL certificates, "letsencrypt" is the way to go.
https://letsencrypt.org/
You don't need to pay anyone for a certificate. Just use LetsEncrypt and their CertBot ACME client. The CertBot automates the task of issuing and renewing certificates.
LetsEncrypt is the leading free SSL certificate authority (CA) and their certs are as good as any paid cert.
i want to transfer my GoDaddy website hosting to EC2 apache. But i do have a confusion that how do i transfer SSL certificates from GoDaddy to EC2 apache.
Do i need to export certificates from GoDaddy?
How to i install those certificates on apache, including priavte key?
Thanks,
Saqib
There is no such thing as transfer SSL certificates when it comes to Apache.
You need to configure Apache server with SSL.
You can refer to the below blog post on how to do so:
