HI i just recently know that it’s possible to develop locally for a template from this link:  
[designers.hubspot.com](https://designers.hubspot.com/docs/tools/local-hubl-server)

### [Local HubL server](https://designers.hubspot.com/docs/tools/local-hubl-server)

The HubL developer server allows web developers that are comfortable with markup and the HubL templating language to build and test HubSpot COS templates locally. The server runs 100% locally with no external dependencies. Once running, you will be…

however i encounter an issue when starting the local server.

OS: OSX  
Java version: 11

I’ve been running into the same issue.

Trying to run local hubl server on a new mac.  
It seems to be some incompatibility with a java library and JDK version.  
Normally I run zsh but I tried in both zsh and bash. Same issue on both.

I really don’t want to figure out how I can do fresh install in docker tho.

Does anyone have the same issue and maybe a better solution?

Hi @beneelen,

for more info. i ran a docker container and install java and cascade it to the team to use since we are using different OS and environments.

i hope below information can help you.

Directory structure:  
/project-name  
- local-hubl-server (unpack zipped)  
- Dockerfile

Dockerfile:  
#assuming latest is ubuntu 18.04

```auto
FROM ubuntu:16.04

MAINTAINER Ken Dela Rama 

RUN apt update && apt -y upgrade && apt install -y default-jre

####### ADD YOUR OTHER STUFF HERE like copy config.yml or anything

CMD /root/local-hubl-server/bin/local-hubl-server && /bin/bash

EXPOSE 8080

```

README.md  
Go to the directory

```auto
Build the Image

> docker build -t local-hubspot .

I prefer the `remove container` after im done

> docker run -rm -it --name local_hubspot -p 8080:8080 -v ${PWD}/local-hubl-server:/root/local-hubl-server local-hubspot

Or use the detached docker container (detached)

> docker run -d -it --name local_hubspot -p 8080:8080 -v ${PWD}/local-hubl-server:/root/local-hubl-server local-hubspot

Stop the container

> docker stop local-hubspot

Start the already ran docker container

> docker start local-hubspot

Access the base directory URL:

> 127.0.0.1:8080 or localhost:8080

```

[@ken\_netfluence](https://community.hubspot.com/t5/user/viewprofilepage/user-id/70380) Thank you very much for outlining your Docker solution to the HubL server issue. I was getting the exact same error you posted originally (“WARNING: An illegal reflective access operation has occurred…”). I’m trying out your method of running HubL with Java inside a Docker container and I’ve almost got it working, however, I’m unable to access the root directory in the browser. When I run

`docker run --rm -it --name local_hubspot -p 8080:8080 -v ${PWD}/local-hubl-server:/root/local-hubl-server local-hubspot`

from your example it shows that the HubL server spins up properly with this message

```auto
INFO [2019-03-05 21:54:16,675] com.yammer.dropwizard.cli.ServerCommand: Starting LocalHubLDevService
INFO [2019-03-05 21:54:17,768] com.hubspot.content.cxu: Local HubL Server started, running at http://127.0.0.1:8080/

```

But when I try to access [http://127.0.0.1:8080/](http://127.0.0.1:8080/) or localhost:8080 in the browser I get an ERR\_EMPTY\_RESPONSE message.

I’m new to Docker and I’m sure I’m missing something quite basic here. Any pointer(s) you (or anyone reading) can offer would be greatly appreciated.

Thank you,

Sam
