I’m trying to connect MySQL with golang using docker, for local MySQL instance it’s working perfectly but when trying to access docker container localhost, always getting connection refused. When it comes to creating a production-grade application, using the environment variable in the application is de facto.. Why should we use the environment variable? GitHub Gist: instantly share code, notes, and snippets. Formatting is a bit of a mess, but it looks to me like you got networking wrong: you don't need the ports directives for the two dbs.
In this tutorial we will focus on reCAPTCHA v2 Google's reCAPTCHA is one of the tool we can use to stop malicious internet bots from abusing our web applications.It comes in two versions, reCAPTCHA v2 and v3. Use os.Environ to list all key/values of the environment.
