Allow public entry and put 6989 as container port
Add encryption key as an setting variable
add 1GB as native storage. Most is 20GB.
Deploy software.
Whole value shall be $0.05/day , and you’ve got a $5 free credit score / month. So it is going to be good for 100 days, which implies you may get scale up your occasion right here.
Customized area may not work primarily based on my testing. Apart from this error for customized area, all works nice.
