Supabase is an interesting cloud implementation of Postgres. You don’t have to do anything now, but just be aware of this. You can easily run postgres for a hobby site on a $5 Digital Ocean droplet with dokku. You can get instances of postgres from AWS, Digital Ocean, GCP, heroku or Azure. You will probably use a database that a cloud provider manages for you online. We’re using a local instance for these demos but for your production applications you won’t use a local docker database. How can I get an instance of postgres online? You might break the database but it’s no big deal, you can always reset it. This will give you a completely fresh database - you’ll have to run the schema creation again.īut understand that it’s safe to explore and try things. Navigate to your github projects folder and For default terminal use: ⌘-space and terminal, enter key. When docker is finished installing move on to cloning the repository. Installing dockerĭownload docker and follow the instructions.Īdd an entry for your local dns to access docker containers (only if you don’t already have this configured). You should avoid using the default schema in postgres because the data there is viewable and can be changed by any database user by default. There is a default schema in postgres called “public”. To use a schema you create it in the RDBMS and then specify the schema name in your connection string. Usually each app will use a named schema for app data. One way that developers can think about schemas is that they are a namespacing feature. Usually only select users can view or modify the tables in a schema so the schema acts a security grouping.Ī schema also contains indexes, functions, stored procedures and things like that. Schemas are used as an administrative grouping of tables. In RDBMS there is a high level concept called a schema that contains tables. Let’s configure a local instance of postgres for this course. Tables are part of schemas and databases contain schemas. The data is stored in a collection of tables. Postgres and most RDBMS have a hierarchical structure. Postgres is free and you can run it on most modern OSs! Both AWS and Azure provide fully managed instances of postgres. Postgres is extensible and has incredible (paid) extensions for specific scenarios like time series and geo-spatial data. Everything you would expect from a modern RDBMS. It has a huge amount of functionality built-in, supports many datatypes including rich support for JSON documents, indexing, replication, security, procedures, full text search, pub-sub etc etc. Postgres is as advanced as any of the paid databases and receives regular updates and support. It was first released in 1996 so it’s been thoroughly battle-tested over the years. Postgres is a relational database but it’s designed and actually used in production for a range of workloads.
