Unable to successfully start the web ui

[stephenlacy]

I have attempted to manually start and run the stack without using the playground with a few issues when accessing the web ui.

Steps to Reproduce (for bugs)

I built and started the stack with the shell scripts, then I attempted to load http://localhost:8080 and got forever-loading empty request.

1. ./build.sh
2. ./deploy_stack.sh

Deploying stack
Creating network func_functions
Creating service func_gateway
Creating service func_alertmanager
Creating service func_nodeinfo
Creating service func_markdown
Creating service func_decodebase64
Creating service func_wordcount
Creating service func_hubstats
Creating service func_prometheus
Creating service func_echoit
Creating service func_base64
Creating service func_webhookstash

• curl localhost:8080/function/func_markdown/ -d "## Testing"
• curl: (56) Recv failure: Connection reset by peer

I inspected the docker network and got the ip for the gateway container, and accessed it via http://<containerid>:8080. I got a white page with just this text: Select a function..

I also manually ran docker-compose build docker-compose up docker-compose down to see if raw compose was a possible solution. I checked but didn't see a particular version of docker that is required.

Am I doing something entirely wrong, or is there a step for setting up the network that I need to do first?
I read all the md files in the repo, your blog post referencing faas, and some of the linked gists without finding a particular solution.

Your Environment

• Docker version version 17.06.0-ce, build 02c1d87

• Operating System and version (e.g. Linux, Windows, MacOS):

Debian Linux 4.9.0-3-amd64

I got it to work by changing the build version of the gateway to the local image: https://github.com/alexellis/faas/blob/master/docker-compose.yml#L10 latest-dev. And changing localhost to 127.0.0.1
Still some form of issue as I needed to change the image.

Hi @stevelacy,

Thanks for your message.

You may have an ipv4/ipv6 conflict on the name localhost in your hosts file such as:

cat /etc/hosts
127.0.0.1	localhost
::1		localhost ip6-localhost ip6-loopback

You can comment out the 2nd line, or use 127.0.0.1 or the IP address of your LAN/WAN connection instead.

Curl can also be forced into ipv4 mode with the -4 flag.

docker-compose is not used for FaaS, but it does have a docker-compose.yml file which is used for creating the Docker stack, so docker-compose up/down/build are not going to be valid.

The tag 0.5.6 for the gateway image is working (I also re-tested it this morning), but you can switch out to a newer (master) version like you did by running ./build.sh and updating the image tag to: latest-dev.

Hope this helps. I'll close the issue for now since you have got up and running, but do re-open if you need to.
