performance test scripts and data

perf

This repository includes scripts for the performance test of harbor.

If you see performance problems please open an issue in repo: goharbor/harbor

How to run the performance tests

To run performance tests for the target harbor instance, first ensure you have the prerequisites:

• Go toolchain
• Git

Then:

1. Clone this repostiroy and generate client from swagger

git clone https://github.com/goharbor/perf
cd perf

2. Prepare user data

export HARBOR_URL=https://admin:[email protected]
export HARBOR_SIZE=small
go run mage.go prepare

3. Run all tests

export HARBOR_URL=https://admin:[email protected]
export HARBOR_VUS=100
export HARBOR_ITERATIONS=200
go run mage.go

The environment variables and targets

The environment variables in the table are the configurations for the performance testing. Use VAR1=value1 VAR2=value2 go run mage.go target format to apply the variables to the testing

Variable	Description	Default value
HARBOR_URL	The url of the harbor will be tested, its format is https?://username:[email protected]
HARBOR_SIZE	The user data size to prepare for the tests	small
HARBOR_VUS	The number of virtual users for the performance test	500
HARBOR_ITERATIONS	The script total iteration limit (among all VUs) for the performance test	1000
K6_ALWAYS_UPDATE	Always install the latest xk6-harbor	false
K6_QUIET	Disable progress updates of the k6	false
K6_CSV_OUTPUT	Make k6 output detailed statistics in a CSV format	false
K6_JSON_OUTPUT	Make k6 output detailed statistics in JSON format	false
HARBOR_REPORT	Whether generate testing report	false

Experimental to send the metrics to the prometheus. (Refer to https://k6.io/docs/results-output/real-time/prometheus-remote-write for more details)

Variable	Description	Default value
K6_PROMETHEUS_RW_SERVER_URL	URL of the Prometheus remote write implementation's endpoint
K6_PROMETHEUS_RW_USERNAME	User for the HTTP Basic authentication at the Prometheus remote write endpoint
K6_PROMETHEUS_RW_PASSWORD	Password for the HTTP Basic authentication at the Prometheus remote write endpoint
K6_PROMETHEUS_RW_TREND_AS_NATIVE_HISTOGRAM	If true, it maps the all defined trend metrics as Native Histograms	false
K6_PROMETHEUS_RW_TREND_STATS	It's a comma-separated list of stats functions	min,p(90),p(95),p(99),max
K6_PROMETHEUS_RW_INSECURE_SKIP_TLS_VERIFY	If true, the HTTP client skips TLS verification on the endpoint	false

The following table includes the targets.

Target	Description	Example
prepare	Generate user data	HARBOR_SIZE=small HARBOR_URL=https://admin:[email protected] go run mage.go prepare
run	Execute a specific test	HARBOR_URL=https://admin:[email protected] go run mage.go run list-projects
all	Execute all tasks	HARBOR_URL=https://admin:[email protected] go run mage.go all
list	Print all test	go run mage.go list
compare	Compare performance	go run mage.go compare 251 252

Performance comparison

Compare the performance of harbor different versions, the format of HTML comparison bar can be generated easily by subcommand. Before you need to retain the outputs folder every time and then rename them to a meaningful name.

For example, if we want to compare the performance of harbor 2.5.1 and 2.5.2, we can just follow the steps:

1. Deploy harbor 2.5.1, prepare data and run tests

  export HARBOR_URL=https://admin:[email protected]
  export HARBOR_SIZE=small
  # prepare data
  go run mage.go prepare
  # run tests
  go run mage.go
  # retain the outputs result
  mv outputs 251 && mkdir outputs

2. Deploy harbor 2.5.2, prepare data and run tests

  export HARBOR_URL=https://admin:[email protected]
  export HARBOR_SIZE=small
  # prepare data
  go run mage.go prepare
  # run tests
  go run mage.go
  # retain the outputs result
  mv outputs 252 && mkdir outputs

3. Compare

 # use outputs result folder name as parameters
 go run mage.go compare 251 252
 # then you can see the comparison in the browser
