Introduce the best practice experience of Go project with a complete project example

$ make docker-compose for app in 'products' 'details' 'ratings' 'reviews' ;
do
GOOS=linux GOARCH="amd64" go build -o dist/$app-linux-amd64 ./cmd/$app/;
GOOS=darwin GOARCH="amd64" go build -o dist/$app-darwin-amd64 ./cmd/$app/;
done for app in 'products' 'details' 'ratings' 'reviews' ;
do
jsonnet -J ./grafana/grafonnet-lib -o ./scripts/grafana/dashboards/$app.json --ext-str app=$app ./scripts/grafana/dashboard.jsonnet ;
done RUNTIME ERROR: couldn't open import "grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths. ./scripts/grafana/dashboard.jsonnet:1:17-53 thunk ./scripts/grafana/dashboard.jsonnet:2:19-26 thunk ./scripts/grafana/dashboard.jsonnet:238:1-10 RUNTIME ERROR: couldn't open import "grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths. ./scripts/grafana/dashboard.jsonnet:1:17-53 thunk ./scripts/grafana/dashboard.jsonnet:2:19-26 thunk ./scripts/grafana/dashboard.jsonnet:238:1-10 RUNTIME ERROR: couldn't open import "grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths. ./scripts/grafana/dashboard.jsonnet:1:17-53 thunk ./scripts/grafana/dashboard.jsonnet:2:19-26 thunk ./scripts/grafana/dashboard.jsonnet:238:1-10 RUNTIME ERROR: couldn't open import "grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths. ./scripts/grafana/dashboard.jsonnet:1:17-53 thunk ./scripts/grafana/dashboard.jsonnet:2:19-26 thunk ./scripts/grafana/dashboard.jsonnet:238:1-10 make: *** [dash] Error 1

不知是哪里不对?

克隆下项目后，直接cd go-project-sample/下运行make docker-compose，发生报错: couldn't open import "grafonnet-lib/grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths

发现下面这个路径下是空的: go-project-sample/scripts/grafana/grafonnet-lib/

建议把https://github.com/grafana/grafonnet-lib/tree/master/grafonnet文件夹直接copy进去，能正常运行。

Problem

The codahale/hdrhistogram repo has been transferred under the github HdrHstogram umbrella with the help from the original author in Sept 2020 (new repo url https://github.com/HdrHistogram/hdrhistogram-go). The main reasons are to group all implementations under the same roof and to provide more active contribution from the community as the original repository was archived several years ago.

The dependency URL should be modified to point to the new repository URL. The tag "v0.9.0" was applied at the point of transfer and will reflect the exact code that was frozen in the original repository.

If you are using Go modules, you can update to the exact point of transfer using the @v0.9.0 tag in your go get command.

go mod edit -replace github.com/codahale/hdrhistogram=github.com/HdrHistogram/[email protected]

Performance Improvements

From the point of transfer, up until now (mon 16 aug 2021), we've released 3 versions that aim support the standard HdrHistogram serialization/exposition formats, and deeply improve READ performance. We recommend to update to the latest version.

老板，我是ubuntu18.04。编译都成功了，就http://localhost:8080/product/1不能访问

我用docker-compose up 发现如下问题： level=warn ts=2020-11-09T07:26:57.142Z caller=notify.go:674 component=dispatcher receiver=email integration=email[0] msg="Notify attempt failed, will retry later" attempts=1 err="establish connection to server: dial tcp: address tcp/port: unknown port" level=error ts=2020-11-09T07:27:17.143Z caller=dispatch.go:309 component=dispatcher msg="Notify for alerts failed" num_alerts=4 err="email/email[0]: notify retry canceled after 7 attempts: establish connection to server: dial tcp: address tcp/port: unknown port" 这两个找不到端口
