This is a simple, command line client for GCloud PubSub emulator. The idea is to help local debug of applications using GCloud PubSub, by providing a simple interface for topic/subscription creation/removal and message publishing.
Run go get github.com/felipebool/gopsub.
gopsub allows you to create, remove and list topics and subscriptions,
and publish messages.
--projector-p: project id
--host: gcloud pubsub emulator host, default value islocalhost--post: gcloud pubsub emulator port, default value is8085
The following command lists all topics for project my-project
gopsub --project my-project topic list
The following command creates a topic called topic1 in project my-project
gopsub --project my-project topic create --id topic1
The following command removes topic topic1 from project my-project
gopsub --project my-project topic remove --id topic1
The following command lists all subscriptions for project my-project
gopsub --project my-project subscription list
The following command creates a subscription called subscription1 in project my-project
gopsub --project my-project subscription create --id subscription1
To create a push subscription, just provide a valid endpoint using --endpoint or -e
gopsub --project my-project subscription create --id subscription1 --endpoint http://localhost/push
The following command removes subscription subscription1 from project my-project
gopsub --project my-project subscription remove --id subscription1
The following command publishes a message passed by --data to topic topic1
gopsub --project my-project publish --topic-id topic1 --data '{"username":"xyz","password":"xyz"}'
If you want to publish more complex data, you can use --data-from-file passing
a path to a file. gopsub will read the content and publish it.
gopsub --project my-project publish --topic-id topic1 --data-from-file /tmp/lol.json
if --data and --data-from-file are both provided, the value passed through --data
will be used.
