UI not starting with ui_dir in config file

[bscott]

I cannot get the UI to start using the ui_dir directive in the config file, only via as a command line flag.

[ryanuber]

@bscott can you show us what the config looks like? Specifying ui as the ui_dir seems to work as expected, as well as specifying an absolute path.

[bscott]

{
"bind_addr": "x.x.x.x",
"bootstrap": false,
"datacenter": "us-west-1.compute.internal",
"data_dir": "/var/lib/consul",
"log_level": "INFO",
"node_name": "ip-1-1-1-3",
"server": true,
"start_join": [],
"ui_dir": "/opt/consul/ui"
}

[armon]

@bscott When you hit the index page (http://localhost:8500/) what do you get? Does it say "Consul Agent" or do a redirect?

Also unrelated, but you will run into issues if you datacenter has periods in it. It makes the DNS parsing ambiguous. Instead, you might try making the datacenter "us-west-1", and if you want, set the domain to "compute.internal".

[bscott]

@armon The node isn't even listening on port 8500

[armon]

The default listen port for HTTP is 8500 unless configured otherwise. Is the agent even starting?

[bscott]

@armon Yes, the agent is starting and joining the cluster.

[armon]

So when it starts, it should log the HTTP port. Can you try to curl port it is logging? Based on the response we can determine if it is loading the UI.

[webcoyote]

I'm able to get the UI working on Linux, but not on Windows (version 0.2.1). Here's the output from curl:

"ui_dir": "C:\\consul\\ui"
"ui_dir": "C:/consul/ui"

I hope that helps you track down the problem.

[armon]

@webcoyote Can you verify if this is happening with the latest build? Might be the same issue of running the older Consul build.

[webcoyote]

@armon: The UI >does< work on Windows when I compiled the latest version from source (re:
#177 (comment)).

[bscott]

I'm still having this issue on latest build with Linux, but I'll test again.

[armon]

Closing. Please re-open if still an issue.

[calvn]

I am encountering this issue. I Can enable the UI on the servers. However on a consul client, requests to http://localhost:8500 and http://localhost:8500/ui/ gives me a 301. Running Consul 0.5.2. on all nodes.

$ curl -v http://127.0.0.1:8500

<a href="/ui/">Moved Permanently</a>.

* Connection #0 to host 127.0.0.1 left intact

The config.json on the client:

{
        "data_dir": "/var/lib/consul",
        "datacenter": "qas",
        "log_level": "INFO",
        "start_join": [<servers>],
        "ui_dir": "/var/lib/consul/ui/dist"
}

Removed start_join servers, but consul members is able to give me back a list of members. Nothing suspicious in the consul logs either, all logs are INFO.

[slackpad]

Hi @cleung2010 - there's no difference in the client vs. server code path that I can see for the server. If you do a curl http://localhost:8500/v1/agent/self?pretty does your UiDir look correctly configured in there? Is it possible you've got another JSON file that's stomping on the one above?

[calvn]

[slackpad]

Actually - I get a 301 when running that curl command locally as well. It kicks you over to the /ui/ page which should serve up index.html. If you tell curl to follow the redirect it should work - curl -L -v http://127.0.0.1:8500.

[calvn]

I get a 200, but the response contains this:

<p>This is an error page for the Consul web UI. You may have visited a URL that is loading an
unknown resource, so you can try going back to the <a href="#">root</a>.</p>

When I curl -v http://127.0.0.1:8500 on the server nodes I get a 200 and Consul Agent on the response

[slackpad]

Hmm - that's actually part of the static index.html page - so it looks like that might be getting served up properly by Consul's web server:

https://github.com/hashicorp/consul/blob/master/ui/index.html#L44-L45

When I curl -v http://127.0.0.1:8500 on the server nodes I get a 200 and Consul Agent on the response

I don't follow what you mean by "Consul Agent on the response" there. Is that not serving up the same index.html?

[hridyeshpant]

i am also getting same issue

HTTP error code from Consul: 0 error
This is an error page for the Consul web UI. You may have visited a URL that is loading an unknown resource, so you can try going back to the root.

inside the host => curl http://localhost:8500/ui/

• Hostname was NOT found in DNS cache
• Trying 127.0.0.1...
• connect to 127.0.0.1 port 8500 failed: Connection refused
• Failed to connect to localhost port 8500: Connection refused
• Closing connection 0
  curl: (7) Failed to connect to localhost port 8500: Connection refused

but when running same command "curl http://localhost:8500/ui/" inside the container , i am getting valid output.

Consul Agent

I also get a 200 and the same response on the body of the client if I do not specify ui_dir. However, as soon as I enable it I get a 301 on both the root and /ui endpoints. Why does root / redirect to /ui, is that intended or is that a side-effect on some misconfiguration on my part?

[calvn]

Noticed that curl -v -L localhost:8500/ serves index.html but it's still in template form, meaning that it's not parsed before being rendered:

<button {{ action "reset" }} {{ bind-attr class=":btn :btn-danger" }}>Reset Defaults</button>

The security group on AWS allows TCP inbound connection from 0.0.0.0/0 to 8500. Networking seems fine too.

@slackpad @hridyeshpant Got it working by adding this to my config.json:

{
    "addresses": {
        "http": "0.0.0.0"
    },
...
}

As explained in #599 the client binds the HTTP address to localhost by default so within the client you're able to curl the /ui endpoint, but you'll just get connection refused if you try to resolve it from the outside.

I'd suggest to update the docs on the Web-UI page so that it explicitly states that the default config only enables the UI within localhost.

@hridyeshpant Can you check the port mapping for that container with docker ps? Perhaps port 8500 is mapped to some other port on the host. https://ewegithub.sb.karmalab.net/EWE/docker/tree/master/stratus/consul/server is not accessible for me.

[slackpad]

@gvenka008c that's the correct behavior - Consul is trying to redirect you to /ui/ which is the location of the web UI. If you add a -L to your curl command it will follow the redirect.

[gvenka008c]

@slackpad Thanks. When I try to hit the URL http://xx.xxx.xxx.xx:8500/ui/ from the browser, it says "Failed to Open Page". I have opened the ports on the server but still the same problem.

# netstat -an | grep 8500
tcp        0      0 127.0.0.1:8500          0.0.0.0:*               LISTEN

@slackpad I started consul with -client argument and that fixed the issues.

consul agent -ui -ui-dir /tmp/consul_web/ -server -bootstrap-expect 1 -data-dir /tmp/consul -node=agent-one -bind=xx.xxx.xxx.xx -config-dir /etc/consul.d -client 0.0.0.0
