尝试使用 docker 执行集成测试。

下面是Dockerfile：

FROM openjdk:8u232

ARG SBT_VERSION=1.2.8

# Install sbt
RUN \
  curl -L -o sbt-$SBT_VERSION.deb https://dl.bintray.com/sbt/debian/sbt-$SBT_VERSION.deb && \
  dpkg -i sbt-$SBT_VERSION.deb && \
  rm sbt-$SBT_VERSION.deb && \
  apt-get update && \
  apt-get install sbt && \
  sbt sbtVersion

ENV WORK_DIR="/test"

USER root

COPY . ${WORK_DIR}/

RUN cd ${WORK_DIR}

RUN sbt clean it:test

下面是docker-compose.yml：

version: '3.7'
services:
  test:
    build:
      context: ../..
      dockerfile: Dockerfile.test
    restart: always

当我运行docker-compose -f test.yaml up 时：

它给了我错误：

Step 10/10 : RUN sbt clean it:test
 ---> Running in d9513c01439b
[warn] No sbt.version set in project/build.properties, base directory: /
[info] Set current project to root (in build file:/)
[success] Total time: 0 s, completed Jun 6, 2020 7:20:37 AM
[error] Expected ';'
[error] No such setting/task
[error] it:test

为了检查它，我从 docker 文件中删除了这一行，并将图像和 exec 构建到容器中，我的测试运行良好。

我的项目结构是：

src
  main
  it
  test

我也尝试过执行单元测试但它给了我：

Step 10/10 : RUN sbt clean test
 ---> Running in c300fcf2bf53
[warn] No sbt.version set in project/build.properties, base directory: /

当我把它改成：

Step 10/10 : CMD sbt clean it:test

如何使用 compose 从 dockerfile 执行 sbt it:test？

【问题讨论】：

标签： scala docker docker-compose sbt

【解决方案1】：

切换到下一个：

RUN cd ${WORK_DIR} && sbt clean it:test

dockerfile中不同的RUN不会互相影响。

【解决方案2】：

如果它在容器内工作，那么这必须工作：

ENTRYPOINT cd ${WORK_DIR} && \
            sbt clean it:test
