earthly特性说明
前边有简单说明以及试用过earthly 以下是功能的一个整体说明（工具真的很不错）
整体说明
- 基容器的构建
- 编程语言无关
- 可重复构建
- 并行执行
- 单体仓库友好
- 多代码仓库友好
核心特性
- 类Dockerfile语法格式
参考
# Initialize the build environment - this applies to all targets.
FROM golang:1.13-alpine3.11
WORKDIR /go-example
build:
# Copy source from local dir into the build environment,
# run go build and save the resulting binary.
COPY main.go .
RUN go build -o build/go-example main.go
SAVE ARTIFACT build/go-example AS LOCAL build/go-example
docker:
# Copy an artifact from target +build,
# set an entrypoint for the image and save it.
COPY +build/go-example .
ENTRYPOINT ["/go-example/go-example"]
SAVE IMAGE go-example:latest
- 构建引用
build:
# Build the target lint (defined in the same build.earth file).
BUILD +lint
# Inherit image from target +some-image available in ./some/deep/dir.
FROM ./some/deep/dir+some-image
# Execute the build of project github.com/some-user/some-project, with
# the target +some-binary, copying the artifact out.
COPY github.com/some-user/some-project+some-binary/out ./
# Execute the build within the local directory ./some/deep/dir, with
# the target +my-binary, copying the artifact bin.
COPY ./some/deep/dir+my-binary/bin ./
lint:
# ...
- 除过images&& artifacts不共享任何东西
a-target:
# Something complex and time-consuming.
another-target:
# Something else complex and time-consuming.
final-target:
# This will build the two targets in parallel.
BUILD +a-target
BUILD +another-target
# So would this.
COPY +a-target/an-artifact ./
COPY +another-target/another-artifact ./
# And so would this (or some other combination).
FROM +a-target
COPY +another-target/another-artifact ./
- 基于buildkit强大的cache能力
- 基于参数的可复用构建
lint:
FROM golang:1.13-alpine3.11
RUN go get golang.org/x/lint/golint
ARG COPY_SRC
COPY "$COPY_SRC" ./
RUN golint -set_exit_status .
lint-project-a:
BUILD --build-arg COPY_SRC=./project-a +lint
lint-project-b:
BUILD --build-arg COPY_SRC=./project-b +lint
- 安全token管理
基于命令行的安全token处理，token 不会存储在镜像中
some-target:
RUN --push --secret GITHUB_TOKEN=+secrets/GITHUB_TOKEN github-release upload file.bin
earth --secret GITHUB_TOKEN --push +some-target
- 支持基于本地以及远程repo 的模式
earth ./path/to/a/deep/dir+target-name
earth github.com/vladaionescu/earthly+earth-docker
同时支持自目录：
earth github.com/vladaionescu/earthly/buildkitd+buildkitd
超越dockerfile 的语法
包含了FROM,COPY,RUN, BUILD ,SAVE,GIT CLONE ....
当然以上的命令包含了好多子命令，都是超越原生dockerfile 的，详细的参考官方文档
说明
earthly 依赖docker但是强大于dockerfile，集成了dockerfile+makefile的强大能力，是一个很不错的基于容器的构建工具
