Lab 10: Connect to source issue about mslearn-postgresql

[HeyMo0sh]

If you are doing it with Azure VM then the public network NSG needs to be set up.
Have you setup the local postgresql instance to be configured to listen for hosts which are not local?

If those work for you then I will write that up - the password not correct when it is says to me that there is something blocking communication from Migrate PostgreSQL to Azure Database for PostgreSQL Flexible Server

[HeyMo0sh]

You have localhost as the server name. The source server has to be accessible to the flexible server, i.e. it has to be accessible from the internet.

So you have to allow your IP address and port 5432 open. Azure won't be able to resolve localhost.
I will document this.

I am testing it outside of VM environment.
I checked the postgresql.conf file and its parameter listen_addresses was already set to '*'.
In the pg_hba.conf file, I added the following line:

host    all    all    0.0.0.0/0    md5

I have also added Firewall rules for port 5432.
After that, I restarted the server and tried connecting to it again using the server's public IP address instead of localhost.
Now the error that I'm getting is:

Failed to connect to server : The operation has timed out.

Are you able to connect to your database from say another Azure VM? you can either telnet to 5432 or using powershell:

Test-NetConnection -ComputerName -Port 5432 -InformationLevel "Detailed"

I found I had to set up a NSG for port 5432 on the VM and also do windows firewall on the VM itself

Having the "local" database in an Azure VM works, so there is probably some additional network setting in my work computer that I need to change before establishing any connections to it through the internet. I reproduced all the configuration steps in both environments but it works only in the VM. I guess we can consider it an edge case and close the issue.

One more thing, in the instructions for Create Database Migration Project in Azure Database for PostgreSQL Flexible Server, step 5 you reference user as demo and its password as Pa$$w0rd for the target server but in this case it should be pgAdmin and the random password generated at the beginning of the lab instructions.

Thanks for spotting that - I have corrected it and pushed to #13
