Golang and uAdmin CI/CD using 🚅Railway!

Steps to Deploy

• Make sure to create a Github account and link it with 🚅Railway
• Click

• Give your new Repository a name (and select the visibility if you want to make it private)
• Set the Environment Variables to the following (you can change the port as per your needs):

Value	env variable
1	CGO_ENABLED
8080	PORT
gcc	NIXPACKS_PKGS
encryption key used for encrypting and decrypting the database	KEY
salt used for encrypting and decrypting the database	SALT

NOTE: The PORT value here needs to match the port where uAdmin is exposed to (the default value is 8080 and I recommend not changing it unless necessary)

• and finally click on Deploy

TA-DA! 🎉 Your app is deployed!

• A github repository will be created with the name you gave in the previous step
• A uadmin instance is run
• It is hosted on a live URL (which you can find in the Deployments tab of your project)
• The expected port is exposed
• An SSL certificate is generated
• A MySQL database is automatically created and linked to uAdmin
• The database is encrypted using the KEY and SALT environment variables

All that with a click of a button and a few environment variables!

Finally, to setup this repository locally, you can follow the steps below:

• Head over to github and clone the repository that was created for you.
• Clicking on MySQL on the railway dashboard will give you the following details:
  • The values for the fields like host, port, user, password and name can be found in the above screenshot from the fields MYSQLHOST, MYSQLPORT, MYSQLUSER, MYSQLPASSWORD and MYSQLDATABSE respectively.

host ⇄ MYSQLHOST

port ⇄ MYSQLPORT

user ⇄ MYSQLUSER

password ⇄ MYSQLPASSWORD

name ⇄ MYSQLDATABSE

• Create a .database file in the root of the repository and add the following content to it using the values mapped from the previous step:

{
  "type": "mysql",
  "name": "railway",
  "user": "root",
  "password": "********************",
  "host": "*********************.railway.app",
  "port": 1234
}

• Create a .encrypt file in the root of the repository and add the following content to it using KEY and SALT environment variables from the railway dashboard:

{
  "KEY": "*********************",
  "SALT": "*********************"
}

You can test the connection to the MySQL instance by running the following command in the root of the repository locally (assuming you have go installed on your machine):

go mod download; go build .; ./railway

Commit these changes to the repository and push them to github.

Now for the cool part!

Since railway automatically deploys the app whenever there is a change in the repository, you will see that a new build is triggered and the app is deployed with the changes you made as soon as you push them to github!

To fix:

[  ERROR ]   Hanlder.NewLogger. Unix syslog delivery error

Update on the above error: The issue is solved in HEAD and will be releases in a new version with the update. (~Internal Sources 👀)
