docker - 无法在最终Docker镜像中显示已安装npm的应用程序

Question

我已将Vega工具的安装添加到docker-asciidoctor Dockerfile中，并且在运行bats测试时它们就存在，但是在运行镜像时它们不再存在。

我是Docker的新手。

我还尝试了将dir node_modules添加到路径的一些变体，但是没有任何效果。

在所有情况下，Vega工具的安装目录都根本不在镜像中。

我正在添加Vega工具，如下所示:

...
  && npm install --build-from-source -g vega-cli vega vega-lite vega-embed \
  && echo `which vl2vg` \
...

提供以下输出:

...
/usr/bin/vl2png -> /usr/lib/node_modules/vega-lite/bin/vl2png
/usr/bin/vl2svg -> /usr/lib/node_modules/vega-lite/bin/vl2svg
/usr/bin/vl2vg -> /usr/lib/node_modules/vega-lite/bin/vl2vg
/usr/bin/vg2pdf -> /usr/lib/node_modules/vega-cli/bin/vg2pdf
/usr/bin/vg2png -> /usr/lib/node_modules/vega-cli/bin/vg2png
/usr/bin/vg2svg -> /usr/lib/node_modules/vega-cli/bin/vg2svg
...
/usr/bin/vl2vg

就像人们期望的那样。

对其中一种工具的测试如下所示:

@test "vl2vg is installed and in the path" {
  docker run -t --rm "${DOCKER_IMAGE_NAME_TO_TEST}" which vl2vg
}

过去了

当执行以下操作时，我希望Vega工具在图像中可用:

docker run -it --entrypoint /bin/sh asciidoctor/docker-asciidoctor
/documents # which vl2vg
which: no vl2vg in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)

给定图像生成的输出，我希望看到 /usr/bin/vl2vg和 /usr/lib/node_modules不存在。

为了完整起见，这里是Docker文件和采取的步骤:

构建命令(从 Makefile提升):

DOCKER_IMAGE_NAME ?= docker-asciidoctor
DOCKERHUB_USERNAME ?= asciidoctor
DOCKER_IMAGE_TEST_TAG ?= $(shell git rev-parse --short HEAD)
build:
    docker build \
        -t $(DOCKER_IMAGE_NAME_TO_TEST) \
        -f Dockerfile \
        $(CURDIR)/

测试是:

test:
    bats $(CURDIR)/tests/*.bats

其中一项测试是上述测试。

造成这种情况的根本原因是，由于未标记图像，所以我没有使用刚刚构建的图像。

docker tag asciidoctor/docker-asciidoctor:442d4d0 asciidoctor/docker-asciidoctor:latest

然后事情就起作用了。
