This repo contains the following plugins:

• app-address - Display addresses of a given app
• env-list - List environment variables of a given app
• goreplay - Sniff the network interface and replay requests on another app

app-address

Display all the addresses of a given app:

»»»» tsuru app-address -a foo-bar
foo-bar.cloud.domain.com
foo-bar.baz.domain.com
foo-bar.baz.globo.com

For one address only:

»»»» tsuru app-address -a foo-bar -o

env-list

List all the environment variables that were set (via env-set) for a given app:

»»»» tsuru env-list -a foo-bar
BAR_ASYNC_TIMEOUT=359
LOG_LEVEL=DEBUG
MONGO_DATABASE=*** (private variable)
MONGO_PASSWORD=*** (private variable)
MONGO_USER=*** (private variable)
NODE_ENV=production
USE_PROXY=true

Display private variables too:

»»»» tsuru env-list -a foo-bar -p
BAR_ASYNC_TIMEOUT=359
LOG_LEVEL=DEBUG
MONGO_DATABASE=my_database
MONGO_PASSWORD=xptoxpto
MONGO_USER=my_user
NODE_ENV=production
USE_PROXY=true

Or specific ones:

»»»» tsuru env-list -a foo-bar -p MONGO_DATABASE MONGO_PASSWORD MONGO_USER
MONGO_DATABASE=my_database
MONGO_PASSWORD=xptoxpto
MONGO_USER=my_user

goreplay

Sniff the network interface and replay requests on another app.

Display installation instructions:

»»»» tsuru goreplay install
To install, add the following to your tsuru.yaml and deploy your app:
hooks:
    build:
        - 'sudo apt-get -y install screen'
        - 'curl -sfSL -o goreplay.tar.gz https://github.com/buger/goreplay/releases/download/v0.16.1/gor_0.16.1_x64.tar.gz'
        - 'tar xvf goreplay.tar.gz'

Replay ALL (!CAUTION!) requests received by app foo-bar-prod on another app (e.g. foo-bar-qa):

»»»» tsuru goreplay start -a foo-bar-prod '--output-http http://foo-bar-qa.domain.com'
Starting...
Done!

Replay 5% of requests:

»»»» tsuru goreplay start -a foo-bar-prod '--output-http "http://foo-bar-qa.domain.com|5%"'
Starting...
Done!

Replay 5% of GET requests:

»»»» tsuru goreplay start -a foo-bar-prod '--output-http "http://foo-bar-qa.domain.com|5%" --http-allow-method GET'
Starting...
Done!

Replay 5% of GET requests on /foo/bar:

»»»» tsuru goreplay start -a foo-bar-prod '--output-http "http://foo-bar-qa.domain.com|5%" --http-allow-method GET --http-allow-url /foo/bar'
Starting...
Done!

Once you're done, stop it:

»»»» tsuru goreplay stop -a foo-bar-prod
Stopping...
Done!

For GoReplay options:

Gor is a simple http traffic replication tool written in Go. Its main goal is to replay traffic from production servers to staging and dev environments.
