如果找不到源命令，Dockerfile构建就会失败。

Question

我正在尝试使用一个v8从源代码构建Dockerfile

FROM ubuntu:20.04

ARG V8_REPO=https://chromium.googlesource.com/chromium/tools/depot_tools.git
ARG ADD_DEPOTTOOLS2PATH='export PATH=/depot_tools:$PATH'

RUN                                         \
apt-get update -y                        && \
apt-get install git -y                   && \
apt-get install vim -y                   && \
apt-get install wget -y                  && \
apt-get install python3 -y               && \
git clone ${V8_REPO}                     && \
echo ${ADD_DEPOTTOOLS2PATH} >> ~/.bashrc && \
source ~/.bashrc

由于某些原因，它在source-ing .bashrc中失败。

$ docker build --tag host --file .\Dockerfile.txt .
...
#5 47.17 /bin/sh: 1: source: not found

executor failed running [... && source ~/.bashrc]: exit code: 127

Answer 1

运行是/bin/sh使用的shell。/bin/sh不提供source命令。尝试.-command而不是source。
