To switch, simply change the DATABASE_URL setting on Heroku. So let's play with it for now, but let's be careful with our sensitive data. Discussing with Amazon, they are aware (of course) of the need and urgency, but didn't risk to share a timeframe. Should the authentication fail with ssl, it will fall back on non-encrypted connection, and since you cannot SSH in either your Heroku instance or your RDS instance, you have no way of verifying (via a tcpdump for instance) that the connection is actually encrypted. Note: if you still value the security group setting, you can use the Proximo add-on that will funnel traffic through a static IP.Ī word of caution: Amazon confirmed that, as of now, it is not possible to force SSL encryption from the DB side. Run heroku config:add EXTERNAL_DATABASE_CA='rds-ssl-ca-cert.pem' (assuming you didn't change the name of the cert).

Copy it in the config/ca dir of your app.

Download the cert file from Amazon (look for the link in the SSL chapter): AWS pgSQL guide.(Well, you could restrict access to the Heroku VPC (098166147350), but it wouldn't be enough of an improvment). This makes the encryption of communications between your servers all the more important. Since Heroku won't give you your machine's IP (or range) you can't restrict the source in the security group. Psql -f latest.sql -host = -port =5432 -username = -password -dbname = Pg_restore -n public -O latest.dump > latest.sqlĪnd then by importing into RDS: # Restore the data on the RDS instance # Replace the with your values # => something like HEROKU_POSTGRESQL_COLOR # add the pgbackups addonĬurl -o latest.dump `heroku pgbackups:url ` # Uncompress it to raw SQL # the -n public option gets rid of commands we wouldn't have access to on RDS

Now that you have both the Heroku DB and the RDS one, we're gonna transfer the data.įirst by exporting the Heroku: # get the name of the heroku DB As with the AZ setting, disable the backups for now if your data set is large.In the config panel, set the db name and choose the security group you just created.

On the details page, choose your instance class, set the storage size, choose an identifier, and set the master username and password to whatever suits you.

If you have no data to transfer, you can enable it.

If your dataset is large, disable the multi-AZ for now.

Now, go to the RDS dashboard and Launch DB Instance. This will allow any source IP to access your DB instance on port 5432.

Select the new group in the list, and in the inbound tab, add a rule.

Name it whatever you want, maybe "RDS-DB", add a description and leave the VPC as the default.

In your AWS console, go to the EC2 dashboard, in the Security Groups tab. This is efficient but it can become complex. You have many variables to play with, classic firewall variables (IP protocol & type, ports), and more AWS-specific like the source network. Even better, you can use several options, adding up and allowing a very granular setting. Basically, it's a set of rules you define to allow access to an instance. Security groups are an important aspect of AWS instances (EC2 and RDS).

Test the procedure on a sample data set.įirst, we have to create a security group:.

Still, there are a few precautionary actions to take before migrating: In this blog post we'll take the easy migration road with a scheduled downtime and manageable data set, and focus on the operational aspects of using AWS RDS. Many things have to be considered, such as the acceptable downtime, the size of the data set, the activity of the app(s) on it… We will assume you already have an application, hosted on Heroku, and an AWS account.ĭepending on your application, migrating data is at least a bit tricky.

Here is a quick run-down on how to achieve this. If you are running your app on Heroku like many Rails developers, you might be interested in using Heroku as your app and web server, and using AWS RDS as your database server with a Postgres engine. log_file: /var/log/postgres/migrate/source_database_05242019.Amazon recently introduced Postgres engine for AWS RDS. backup_dir: /dbbackup/10/source_database Make Sure to Review the Commands Before Execution 05-24-2019 22:14:08 - DURATION: BEGIN Paste in the below contents: chmod +x migrateDB_parallel.shīackup_dir=$ĭest_.

The following is a step-by-step guide to migrating your PostgreSQL on-premise databases to the cloud using Amazon RDS.
