Local by Flywheel Regenerating Machine Certificates

Recently, when I tried to run Local by Flywheel I received the notification

Regenerating Machine Certificates
Local detected invalid Docker Machine TLS certificates and is fixing them now.

Unfortunately this notification kept popping up over and over and Local by Flywheel was unusable.

This thread on the Local by Flywheel support forum provided the solution but required some hunting so I’m documenting this here.

Step 1: Quit Local

Quit local.

Step 2: Create Docker Alias

From the command line, run

alias local-docker-machine="/Applications/Local\ by\ Flywheel.app/Contents/Resources/extraResources/virtual-machine/vendor/docker/osx/docker-machine"

and wait for it to complete.

Step 3: Regenerate Certs

When the previous command has finished, from the command line, run

local-docker-machine stop local-by-flywheel; rm -rf ~/.docker/machine/certs; local-docker-machine create local-cert-gen; local-docker-machine start local-by-flywheel; local-docker-machine regenerate-certs -f local-by-flywheel; local-docker-machine rm -f local-cert-gen;

and wait for it to complete.

Step 4: Re-open Local

At this point, Local by Flywheel functioned properly.
