[英]Install maven/java packages inside docker image without starting springboot
[英]Cannot Install R Packages in Docker Image
似乎由於法律原因,Java無法在docker鏡像中單獨安裝,而是我們必須使用java鏡像。
我正在使用一個java映像,根據需要安裝了R,但是當我安裝R包時出現錯誤
這是我的Dockerfile如下:
FROM buildpack-deps:jessie-scm
# A few problems with compiling Java from source:
# 1. Oracle. Licensing prevents us from redistributing the official JDK.
# 2. Compiling OpenJDK also requires the JDK to be installed, and it gets
# really hairy.
RUN apt-get update && apt-get install -y --no-install-recommends \
bzip2 \

# based on whether the JDK or only the JRE is installed
RUN { \

echo 'set -e'; \

echo 'dirname "$(dirname "$(readlink -f "$(which javac || which java)")")"'; \
} > /usr/local/bin/docker-java-home \

RUN R -e "install.packages('reshape2')"
RUN R -e "install.packages('igraph')"
# copy the app to the image
RUN mkdir /root/testapp1
COPY testapp1 /root/testapp1
COPY Rprofile.site /usr/lib/R/etc/
EXPOSE 3838
CMD ["R", "-e shiny::runApp('/root/testapp1')"]
當我嘗試安裝任何R包時,我得到以下錯誤:
> install.packages('shiny')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Error in contrib.url(repos, type) :
trying to use CRAN without setting a mirror
Calls: install.packages -> grep -> contrib.url
Execution halted
The command '/bin/sh -c R -e "install.packages('shiny')"' returned a non-zero code: 1
我怎樣才能解決這個問題的頭痛問題。
謝謝。
當在R環境中執行install.packages('shiny')
,它會掛起,要求您從要下載的鏡像中進行選擇。
> install.packages('shiny')
Installing package into ‘/Users/user/Library/R/3.3/library’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---
HTTPS CRAN mirror
1: 0-Cloud [https]
2: Algeria [https]
...
55: (HTTP mirrors)
Selection:
根據你的錯誤輸出似乎命令RUN R -e "install.packages(c('shiny', 'rmarkdown'), repos='https://cloud.r-project.org/')"
然后執行下一個,然后在嘗試執行時失敗(錯誤退出1):
RUN R -e "install.packages('shiny')"
相反, install.packages('shiny', repos='https://cloud.r-project.org/')
可能會進行靜默安裝,而不會提出任何問題。
看起來你得到的錯誤來自install.pacakges
方法,這些方法沒有指定repos參數。
一旦我使用你的dockerfile在我的本地機器上使用repos='http://cran.us.r-project.org/'
更新了install.packages
,圖像就成功構建了。
