shell string uppercase lowercase turn
uname -s | awk '{print tolower($0)}'
shell string concatenation
For the connection string or variable, shell provides a very simple approach
Put together directly or can be enclosed in double quotes
${staticTag} ${timeTag} ${branchFlag} ${commitFlag} ${goVersionFlag}
Additional information is compiled with golang
golang we can use at compile time -ldflagsthe compiler option to add some information that is written to the target file
Cross compiler
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build main.go CGO_ENABLED=0 GOOS=windows GOARCH=amd64 go build main.go
GOOS: target platform operating system (darwin, FreeBSD, Linux, Windows)
GOARCH: architecture target platform (386, amd64, arm)
cross-compiler does not support CGO so to disable it
