Docker compose not working
Closed this issue · 3 comments
Hello,
After look at integrating Engine into a desktop app, I wanted to try the server edition afterall. To be quick and easy, I wanted to use the docker compose script provided but they don't work out of the box. Seems like either (or both) vanilla config of a Windows installation of Docker doesn't work and some files are missing or misplaced.
I'm not really use to config file for docker-composer, but since the log seems to talk about filesharing, I looked a bit into that. Right off the hook, it seems that the dbdata folder for the db services doesn't exist. Same goes for the dockerfile itself in workflowserver service, it is not in the folder stated in the config ./WorkflowServer/Dockerfile (so, since it's a dot, it should be found in docker-compose/postgresql/WorkflowServer, yet it is nowhere to be found, even elsewhere in the repository. Again, the log folder, same thing, doesn't exist to start with. So I don't know which one is causing the issues, but clearly the non-existing dockerfile is a probable cause to start with.
I've tried the export COMPOSE_CONVERT_WINDOWS_PATHS=1, didn't change the result below.
Anything else to look after?

D:\HIDDEN\workflowEngine\WorkflowServer\docker-compose\postgresql>docker-compose up workflowserver
Building workflowserver
ERROR: Cannot locate specified Dockerfile: ./WorkflowServer/DockerfileOne step further, I replaced the build: context: ../.. dockerfile: ./WorkflowServer/Dockerfile section with image: optimajet/workflowserver. I also changed the settings in Docker about allowed sub folder to be mounted in Docker. And using the cmd instead of Powershell. I was able to go farther, but not yet launched.
It seems that the stard_db services is not able to read the shell script, and then workflow server can't start up. I got this error. Seems related to the database... Should I init the database first? Should a docker install take care of that?

So, I did have to run the initial SQL script for it to run.
As a suggestion, could it be possible for a docker install to be more friendly. Maybe letting know in the manual the file sharing potential issue on windows, and that SQL script must be run manually (or even better, make them work during the first launch!)
Hi, thank you for the report. We have fixed it. New instructions https://workflowengine.io/documentation/workflow-server/how-to-launch/#docker
