在Docker容器上运行水管工API

我想在Docker容器上运行管道工API

我尝试了以下两个DockerFile：

第一个Dockerfile

FROM rstudio/plumber
MAINTAINER Docker User <docker@user.org>
RUN R -e "install.packages('broom')"
RUN mkdir -p ~/application

# copy everything from the current directory into the container
COPY "/" "application/"
WORKDIR "application/" 

# open port 80 to traffic
EXPOSE 80

# when the container starts, start the main.R script
ENTRYPOINT ["Rscript", "execute_plumber.R"]

两者都导致了以下错误：

* Downloading renv 0.12.0 from CRAN archive ... OK
* Installing renv 0.12.0 ... Done!
Successfully installed and loaded renv 0.12.0.
Error in library(plumber) : there is no package called ‘plumber’
Execution halted

对于第二个Dockerfile，我还尝试安装不同的linux库，例如

git-core
libcurl4-openssl-dev
xml2 openssl

他们都没帮上忙

我正在Azure上运行它。有什么建议吗

更新 在容器构建日志文件中，我可以清楚地看到

管道工

已成功安装

> install.packages('plumber')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
also installing the dependencies ‘curl’, ‘Rcpp’, ‘later’, ‘BH’, ‘rlang’, ‘glue’, ‘R6’, ‘stringi’, ‘jsonlite’, ‘webutils’, ‘httpuv’, ‘crayon’, ‘promises’, ‘sodium’, ‘swagger’, ‘magrittr’, ‘mime’, ‘lifecycle’

...

* DONE (plumber)

在此输出中：

> install.packages('plumber')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
also installing the dependencies ‘curl’, ‘Rcpp’, ‘later’, ‘BH’, ‘rlang’, ‘glue’, ‘R6’, ‘stringi’, ‘jsonlite’, ‘webutils’, ‘httpuv’, ‘crayon’, ‘promises’, ‘sodium’, ‘swagger’, ‘magrittr’, ‘mime’, ‘lifecycle’

...

* DONE (plumber)

看起来程序包正在安装到R站点库中，但是：

* Downloading renv 0.12.0 from CRAN archive ... OK
* Installing renv 0.12.0 ... Done!
Successfully installed and loaded renv 0.12.0.
Error in library(plumber) : there is no package called ‘plumber’
Execution halted

项目的

renv

自动加载程序（通常是项目

.Rprofile

的一部分）正在运行，这将设置项目使用私有库路径（与站点库隔离）

我怀疑您可以通过重新组织Dockerfile中的命令来解决这个问题；e、 g

FROM rocker/r-ver:4.0.2

# install the linux libraries needed for plumber
RUN apt-get update -qq && apt-get install -y \
  libssl-dev \
  libcurl4-gnutls-dev

# create the application folder
RUN mkdir -p ~/application

# copy everything from the current directory into the container
COPY "/" "application/"
WORKDIR "application/" 

# open port 80 to traffic
EXPOSE 80

# install plumber
RUN R -e "install.packages('plumber')"

# when the container starts, start the main.R script
ENTRYPOINT ["Rscript", "execute_plumber.R"]

---

换句话说，请确保在设置工作目录后调用

install.packages（“水管工”）

。

谢谢，我会尝试一下，但我认为

COPY

命令将失败，因为

RUN mkdir-p~/application

只在稍后执行，而且目录不存在yetSorry，是--应该更早地移动该命令。我将编辑我的回复。谢谢你，你的建议奏效了。容器现在正在运行，现在我需要能够访问我的API，但这是不同的问题

FROM rocker/r-ver:4.0.2

# install the linux libraries needed for plumber
RUN apt-get update -qq && apt-get install -y \
  libssl-dev \
  libcurl4-gnutls-dev

# create the application folder
RUN mkdir -p ~/application

# copy everything from the current directory into the container
COPY "/" "application/"
WORKDIR "application/" 

# open port 80 to traffic
EXPOSE 80

# install plumber
RUN R -e "install.packages('plumber')"

# when the container starts, start the main.R script
ENTRYPOINT ["Rscript", "execute_plumber.R"]
