  Database is already created in Postgres. pgloader mysql: / / user :password @localhost / mydb postgresql: / / user :password @localhost / mydb You can also use a load file to make the tables public after import. Add this to a file (e.g load_file.load): LOAD DATABASE FROM mysql: / / root:mysql @localhost / from_db_name INTO postgresql: / / localhost / to_db_name ALTER schema 'to_db_name' rename to 'public' ; And run: $ pgloader load_file.load

Solution 1: For someone that may come across this as I did, I found the solution to be   setting up the Health Check endpoint of the ELB target group to an actual URL on my website that returned an HTTP 200 code . On the EC2 dashboard, under Load Balancing -> Target Groups, go to the tab Health Checks and edit the path to a path in your site that returns an 200 code. Solution 2: Change the health check's "Success codes" setting from  200  to  200,301 View image - EC2 -> Load Balancing -> Target Groups

Apache Add the following block to your  .htaccess  file: <FilesMatch ".(eot|otf|ttf|woff|woff2)"> Header always set Access-Control-Allow-Origin "*" </FilesMatch> Nginx Add the following location block to your virtual host file (usually within the server directive) and reload Nginx: location ~* \.(eot|otf|ttf|woff|woff2)$ { add_header Access-Control-Allow-Origin *; } Invalidate CloudFront Distribution Once the changes have been made you will need to  invalidate the CloudFront cache  with a path of “/*”. Integrating to CloudFront service It’s simple to config and use CloudFront (a CDN service) for Rails app.  Just one thing from my experience, regarding to CORS issue on EB when your CSS want get loading font files or font-awesome. Because EB run your app with Nginx server serve public static files, then work around would be overwriting web server config in Nginx with  add_header Access-Control-Allow-Origin ‘*’  by crea
