Hi to all,

I just installed the latest tyk_quickstart in a Docker 1.9 env

Where creating a key I receive the error:

Failed to save new session object to Tyk: Failed to create key: Post http://ambassador_1:8080/tyk/keys/create: dial tcp 172.17.0.2:8080: getsockopt: connection refused

The API (in Open auth mode) works well.

Here my docker-compose.yml:

ambassador:
image: cpuguy83/docker-grand-ambassador
volumes:
- /var/run/docker.sock:/run/docker.sock
command: “-name tykquickstart_tyk_gateway_1 -name tykquickstart_tyk_dashboard_1”
tyk_gateway:
image: tykio/tyk-gateway:latest
links:
- tyk_redis:redis
- tyk_mongo:mongo
- ambassador:tyk_dashboard
ports:
- “80:8080”
- “8080:8080”
volumes:
- ./tyk.conf:/opt/tyk-gateway/tyk.conf
tyk_dashboard:
image: tykio/tyk-dashboard:latest
links:
- tyk_redis:redis
- tyk_mongo:mongo
- tyk_gateway:tyk_gateway
- ambassador:tyk_gateway
ports:
- “3000:3000”
volumes:
- ./tyk_analytics.conf:/opt/tyk-dashboard/tyk_analytics.conf
tyk_redis:
image: redis:latest
hostname: redis
tyk_mongo:
image: mongo:latest
command: [“mongod”, “–smallfiles”]
hostname: mongo

Thanks in advance for any support !

Hi Gian Luca,

There’s the problem:

If you look at the compose yal, we specify the services for the ambassador as:

command: “-name tykquickstart_tyk_gateway_1 -name tykquickstart_tyk_dashboard_1”

And your docker-compose is starting them as a different name:

tykquickstartmaster_tyk_dashboard_1

tykquickstartmaster_tyk_gateway_1

You will need to edit the compose yaml to use these in the “command” section, so change it to:

command: “-name tykquickstartmaster_tyk_dashboard_1 -name tykquickstartmaster_tyk_gateway_1”

This should work, though I’m not sure what the ambassador is called internally, with any luck it will still be the same name.

Cheers,
Martin

Hi Gian Luca,

Have you docker pulled the :latest tag for tyk-gateway and tyk-dashboard?

Are all of the docker containers running? Which ones are running?

What you are seeing is Tyk Dashboard trying to communicate with the gateway to generate a key, but it can’t connect via the ambassador.

Not sure how to resolve this - have you changed anything in the setup? How did you bootstrap the instance? have you modified the tyk.conf file in any way?

Cheers,
Martin

Hi Martin,

I deploy a new Tyk instance using docker composer just on last friday:

docker-compose up -d

and setup using

./setup.sh 127.0.0.1 myhost.mydomain.com

My current container situation is (docker ps):

0c8ac3be44e1 tykio/tyk-dashboard:latest “/opt/tyk-dashboard/t” 3 days ago Up 4 hours 0.0.0.0:3000->3000/tcp tykquickstartmaster_tyk_dashboard_1
47613c4f45f6 tykio/tyk-gateway:latest “/opt/tyk-gateway/tyk” 3 days ago Up 4 hours 0.0.0.0:8080->8080/tcp, 0.0.0.0:80->8080/tcp tykquickstartmaster_tyk_gateway_1
e52ff70bc8c5 redis:latest “/entrypoint.sh redis” 3 days ago Up 4 hours 6379/tcp tykquickstartmaster_tyk_redis_1
ee4a986ae634 mongo:latest “/entrypoint.sh mongo” 3 days ago Up 4 hours 27017/tcp tykquickstartmaster_tyk_mongo_1
24e4fcc3a6cc cpuguy83/docker-grand-ambassador “/usr/bin/grand-ambas” 3 days ago Up 4 hours tykquickstartmaster_ambassador_1

I didn’t make any modifications at configuration (tyk.conf), but it seems that ambassador have no port configured …

Hope this helps !

Hi Martin,

your suggestion works perfectly !!

Take into account that the original yml at

https://github.com/lonelycode/tyk_quickstart/blob/master/docker-compose.yml

is wrong :wink:

Thank you for your support !

Best Regards.

Hi Gian Luca,

It might be wrong for your OS, seems to be that docker-compose is inconsistent across distros, so the sample works fine for Kitematic / OSX, and older versions of docker_compose, so it’s dependent on what you are running.

Cheers,
M.
