Mysql connection not using the host and port specified

[Bryce Large]

Hi there,

Here is the docker run script:

docker run
  -d
  --name='semaphore'
  --net='bridge'
  -e 'SEMAPHORE_DB_DIALECT'='mysql'
  -e 'SEMAPHORE_ADMIN'='admin'
  -e 'SEMAPHORE_ADMIN_PASSWORD'='somepass'
  -e 'SEMAPHORE_ADMIN_NAME'='someone'
  -e 'SEMAPHORE_ADMIN_EMAIL'='someone@somewhere'
  -e 'SEMAPHORE_ACCESS_KEY_ENCRYPTION'='9946NyKhSqwfqeqwfqwfqwfqw5CH+kg='
  -e 'SEMAPHORE_DB_HOST'='192.168.1.2'
  -e 'SEMAPHORE_DB_PORT'='3309'
  -e 'SEMAPHORE_DB_USER'='semaphore'
  -e 'SEMAPHORE_DB_PASS'='somepassword'
  -e 'SEMAPHORE_DB'='semaphore'
  -p '3000:3000/tcp'
  -v '/semaphore':'/config':'rw' 'ghcr.io/imagegenius/semaphore' 

Here is the container errors:

/go/src/github.com/ansible-semaphore/semaphore/cli/main.go:8 +0x17

what does printenv show within the container?

PS1 value is suspect but dont think that would cause this issue

It is indeed working, looks like mysql is not configured so that the user semaphore is allowed to connect from 172.17.0.1, update the user so that it allows connections from anywhere % or 172.17.0.1

Thanks for the quick assistance.

Tried that, perhaps its not connecting to the correct port, I have mysql running on many ports. Let me test the 3306 instance

[Bryce Large]

Confirmed its connecting to 3306 not the specified SEMAPHORE_DB_PORT of 3309

is this a limitation of semaphore or is there something else going on?

Semaphore requires the port be part of SEMAPHORE_DB_HOST as it knows nothing about SEMAPHORE_DB_PORT. e.g. SEMAPHORE_DB_HOST=192.168.0.2:4306

https://docs.semui.co/administration-guide/installation#docker, SEMAPHORE_DB_PORT is marked as a variable here

Yes but the Semphore code doesn't do anything with SEMAPHORE_DB_PORT. The port needs to be specified with SEMAPHORE_DB_HOST. SEMAPHORE_DB_PORT simply isn't implemented (yet).
