How to configure docker and postgres to use pact broker - postgresql

Question

localhost to view pacts
I have installed brew version of postgres and docker.
Followed the steps in the link https://github.com/DiUS/pact_broker-docker/blob/master/POSTGRESQL.md to create a dockerised pact broker and postgres.
When I run the first command, container got created with error:
docker run --name pactbroker-db -e POSTGRES_PASSWORD=ThePostgresPassword -e POSTGRES_USER=admin -e PGDATA=/var/lib/postgresql/data/pgdata -v /var/lib/postgresql/data:/var/lib/postgresql/data -d postgres
Response:
b8a2007e5dac9554e0ac615147d74467ceb6043dba027a4a21388721cee8f34c
docker: Error response from daemon: Mounts denied:
The path /var/lib/postgresql/data
is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing...
Somehow managed to bypass the first step by removing the bind volume option:
docker run --name pactbroker-db -e POSTGRES_PASSWORD=ThePostgresPassword -e POSTGRES_USER=admin -e PGDATA=/var/lib/postgresql/data/pgdata -d postgres
Succeeded 2 and 3 steps in the link specified:
(2)Connect to the container and execute psql via:
(3)Start the PactBroker container via:
After this, tried to curl json using the below command:
curl -v -XPUT -H “Content-Type: application/json” -d #/HelloWorldConsumer-HelloWorldProvider.json http://localhost/pacts/provider/HelloWorldProvider/consumer/HelloWorldConsumer/version/1.0
Getting the below response...
Could not resolve host: application
* Closing connection 0
curl: (6) Could not resolve host: application
* Trying ::1...
* connect to ::1 port 80 failed: Connection refused
* Trying 127.0.0.1...

* Connection #1 to host localhost left intact
Not sure whether its success or failure as the first line saying... 'Couldn't resolve host:application' and 'Closing connection'
And when I tried to view the localhost, it appears blank.
Screenshot attached.
Looking out for help as early as possible !! Thanks in advance...

Answer 1

It seems you are attempting to mount a volume on your host machine (/var/lib/postgresql/data) that does not exist.
docker: Error response from daemon: Mounts denied:
The path /var/lib/postgresql/data
is not shared from OS X and is not known to Docker.
The message clearly states this. You should read more about docker volumes, but I'd suggest you mount another directory if this is for development on your Mac.
Secondly, you can see that you're getting an "Unsupported media type" on the upload so it has definitely failed:
HTTP/1.1 415 Unsupported Media Type
It appears as though the Content-Type is not being correctly set, you can see this in the output:
Content-Type: application/x-www-form-urlencoded
Please check that the file actually exists at path /HelloWorldConsumer-HelloWorldProvider.json, that it is a valid JSON file, and that your content type header is formatted correctly (it appears to be).
