Port-forwarding to service not working on 0.12.49 ...

Hi everyone, I'm experiencing port-forwarding issues on garden 0.12.49 and above (we are not ready to upgradeto Bonsai yet). On 0.12.48 I can run a simple

mysql -u root -h 127.0.0.1 -p

and successfully connect to my database. On 0.12.49 and above that command results in this error

ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (61)

I started garden in silly debug mode on each version. When connecting to mysql on 0.12.48 I see the following output from garden

Copy code

ℹ mysql [debug]             → Starting port forward to mysql/mysql:3306

On 0.12.49 I get no output. However, I am able to connect on 0.12.49 and above if I use the following command

mysql -u root -h localhost --protocol=tcp -p

. The same command with

127.0.0.1

as the host results in the error mentioned above. I have create a simple garden project with a mysql 8 database at https://github.com/ultimatemonty/garden-localhost-port-forwarding-repro that can be used to test. The repo includes the yaml output for my project resources as well as all resources in the garden-system namespace for 0.12.48 and 0.12.49. A cursory diff of the resources didn't reveal anything interesting - mostly metadata changes. I also looked over the diff from 0.12.48 to 0.12.49 (https://github.com/garden-io/garden/compare/0.12.48...0.12.49?diff=split) and nothing stood out as a potentially suspicious change. This seems similar to https://discord.com/channels/817392104711651328/1065773860328325140/1065773860328325140.

this is not just a MySQL issue. My users are also experiencing the issue when trying to perform remote debugging on a java project.

kubectl port-forward

works for them but is definitely not ideal

update: I was able to use the

GARDEN_DEFAULT_PROXY_ADDRESS

environment variable to fix the issue per https://github.com/garden-io/garden/pull/3690
