docker pull garima0079/bigimage
docker tag garima0079/bigimage {harbor LB地址}/bigimage
docker push {harbor LB地址}/bigimage

测试工具准备:

1
2
3
git clone git@github.com:seamounts/perftest.git -d $GOPATH/src
cd $GOPATH/src/perftest
go build

准备测试集群node docker daemon 配置:

批量更新 k8s node docker daemon，将 harbor lb地址加入到 insecure-registries 列表

1
$GOPATH/src/perftest/cmd/harbor/script/prepare.sh

清除镜像缓存:

批量清除 k8s node 节点镜像缓存

1
$GOPATH/src/perftest/cmd/harbor/script/clear-image-cache.sh {harbor LB地址}/bigimage

测试指标

镜像无缓存并发拉取大镜像的平均耗时，99值耗时

harbor 实例数和拉取时间的关系

harbor 支持的最大并发

无缓存拉取大镜像测试

2 HA harbor测试

测试环境：

harbor 性能总结

2 HA harbor 性能

2.1 并发拉取镜像数和拉取延迟关系

1

拉取 1.7G 大镜像所需要的时间和并发拉取node的数量基本成线性正比的关系，并发度每增加100，拉取时间就相应增加一分钟。

2.2 并发拉取镜像数和cpu 使用率关系

2

并发拉取量每增加 100，cpu 使用率就增加 10%，当并发达到 500 时，cpu使用率为50%左右 。可知当拉取镜像的并发数达到500以上时，对 harbor 的压力会比较大。

推荐增加harbor 实例个数来缓解压力。

2 HA harbor 和 4HA harbpr 拉取镜像平均时间对比

50 nodes 100 nodes 300 nodes
2HA harbor 49.8971 s 70.0965 s 152.4312 s
4HA harbor 45.7705 s 70.5216 s 138.6291 s

增加 harbor 实例个数，拉取镜像所花费时间没有明显的的减少。时间增加应该和后端存储的性能和网络带宽有关。
