docker - parse_repo_spec(repo) 错误 : Invalid git repo specification: 'rga'

Question

我对 Docker 概念比较陌生，我正在尝试对我构建的 Shinys 应用程序之一进行 docker 化。

因为我正在处理 Google 分析数据 其中一个依赖项来自 github 存储库，我在其中使用名为 rga 的包。存储库的链接是 https://github.com/skardhamar/rga

下面是我按照这篇文章创建的 Docker 文件 https://www.bjoern-hartmann.de/post/learn-how-to-dockerize-a-shinyapp-in-7-steps/

# Install R version 3.5
FROM r-base:3.5.0

# Install Ubuntu packages
RUN apt-get update && apt-get install -y \
    sudo \
    gdebi-core \
    pandoc \
    pandoc-citeproc \
    libcurl4-gnutls-dev \
    libcairo2-dev/unstable \
    libxt-dev \
    libssl-dev

# Download and install ShinyServer (latest version)
RUN wget --no-verbose https://s3.amazonaws.com/rstudio-shiny-server-os-build/ubuntu-12.04/x86_64/VERSION -O "version.txt" && \
    VERSION=$(cat version.txt)  && \
    wget --no-verbose "https://s3.amazonaws.com/rstudio-shiny-server-os-build/ubuntu-12.04/x86_64/shiny-server-$VERSION-amd64.deb" -O ss-latest.deb && \
    gdebi -n ss-latest.deb && \
    rm -f version.txt ss-latest.deb

# Install R packages that are required
# TODO: add further package if you need!
RUN R -e "install.packages(c('shiny', 'shinydashboard', 'dplyr', 'ggplot2', 'bigrquery', 'devtools'), repos='http://cran.rstudio.com/')"
RUN R -e "devtools::install_github('rga', 'skardhamar')"

# Copy configuration files into the Docker image
COPY shiny-server.conf  /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/

# Make the ShinyApp available at port 80
EXPOSE 80

# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh

CMD ["/usr/bin/shiny-server.sh"]

但是，在尝试构建 docker 镜像时会抛出如下错误

Error in parse_repo_spec(repo) : Invalid git repo specification: 'rga'
Calls: <Anonymous> -> lapply -> FUN -> parse_git_repo -> parse_repo_spec
Execution halted

当变为

RUN R -e "devtools::install_github("rga", "skardhamar")"

出现以下错误:

Error in lapply(repo, github_remote, ref = ref, subdir = subdir, auth_token = auth_token,  :
  object 'rga' not found
Calls: <Anonymous> -> lapply
Execution halted

Answer 1

我设法通过使用

解决了这个问题

RUN R -e "devtools::install_github('skardhamar/rga')"
