我收到如下錯誤：
#8 46.51 [error] java.lang.IllegalStateException: cannot run sbt from root directory without -Dsbt.rootdir=true; see sbt/sbt#1458
#8 46.51 [error] Use 'last' for the full log.
Dockerfile 主要只是下載和安裝 debian。但是有些事情讓 sbt 不開心。不知道是什么。
FROM openjdk:8 as build
ENV SBT_VERSION "1.5.8"
ENV APP_HOME /service
# Install sbt
RUN \
curl -L -o sbt-$SBT_VERSION.deb https://repo.scala-sbt.org/scalasbt/debian/sbt-$SBT_VERSION.deb && \
dpkg -i sbt-$SBT_VERSION.deb && \
rm sbt-$SBT_VERSION.deb && \
apt-get update && \
apt-get install sbt && \
sbt sbtVersion

我相信問題是使用 root aka/作為作業目錄。WORKDIR /home在RUN ...命令修復docker build ...錯誤之前添加，我能夠docker run ...成功。
docker build ...
docker build -f Dockerfile.so -t 70625015:latest .

從錯誤的外觀來看，您嘗試在RUN命令之前添加
最終結果將是
FROM openjdk:8 as build
ENV SBT_VERSION "1.5.8"
ENV APP_HOME /service
WORKDIR /app
# Install sbt
RUN \
curl -L -o sbt-$SBT_VERSION.deb https://repo.scala-sbt.org/scalasbt/debian/sbt-$SBT_VERSION.deb && \
dpkg -i sbt-$SBT_VERSION.deb && \
rm sbt-$SBT_VERSION.deb && \
apt-get update && \
apt-get install sbt && \
sbt sbtVersion
