Docker-compose共享包含器之间的dirs

我的docker组成连接3容器：rstudio，selenium服务器和shiny的服务器。 我想将R库的dirs从rstudio容器共享到闪存容器，以便轻松pipe理R包，因为我在rstudio容器中工作。 但是，当我共享卷pkgs和pkgs2 ，rstudio容器中没有包：

 > list.files("/usr/local/lib/R/site-library") [1] "backports" "base64enc" "bitops" "caTools" "digest" "docopt" [7] "evaluate" "highr" "htmltools" "httpuv" "jsonlite" "knitr" [13] "magrittr" "markdown" "mime" "R6" "Rcpp" "rmarkdown" [19] "rprojroot" "shiny" "sourcetools" "stringi" "stringr" "xtable" [25] "yaml" > list.files("/usr/local/lib/R/library") [1] "base" "compiler" "datasets" "graphics" "grDevices" "grid" [7] "methods" "parallel" "splines" "stats" "stats4" "tcltk" [13] "tools" "translations" "utils" 

而不是（当卷pkgs和pkgs2从rstudio服务中删除）：

  > list.files("/usr/local/lib/R/site-library") [1] "acepack" "AnnotationDbi" "AnnotationFilter" [4] "AnnotationHub" "assertthat" "backports" [7] "base64enc" "BH" "bindr" [10] "bindrcpp" "binman" "Biobase" [13] "BiocGenerics" "BiocInstaller" "BiocParallel" [16] "biomaRt" "Biostrings" "biovizBase" [19] "bit" "bit64" "bitops" [22] "blob" "brew" "BSgenome" [25] "caTools" "checkmate" "cluster" [28] "codetools" "colorspace" "commonmark" [31] "crayon" "curl" "data.table" [34] "DBI" "DelayedArray" "desc" [37] "devtools" "dichromat" "digest" [40] "divosR" "docopt" "doParallel" [43] "dplyr" "DT" "ensembldb" [46] "EnsemblRest" "evaluate" "foreach" [49] "foreign" "formatR" "Formula" [52] "futile.logger" "futile.options" "GenomeInfoDb" [55] "GenomeInfoDbData" "GenomicAlignments" "GenomicFeatures" [58] "GenomicRanges" "getopt" "ggplot2" [61] "git2r" "GLU" "glue" [64] "gridBase" "gridExtra" "grImport" [67] "gtable" "Gviz" "highr" [70] "Hmisc" "htmlTable" "htmltools" [73] "htmlwidgets" "httpuv" "httr" [76] "igis" "igraph" "interactiveDisplayBase" [79] "IRanges" "irlba" "iterators" [82] "jsonlite" "knitr" "labeling" [85] "lambda.r" "lattice" "latticeExtra" [88] "lazyeval" "lintr" "littler" [91] "magrittr" "markdown" "MASS" [94] "Matrix" "matrixStats" "memoise" [97] "mime" "miniUI" "mongolite" [100] "munsell" "NMF" "nnet" [103] "openssl" "pbapply" "pkgconfig" [106] "pkgmaker" "plogr" "plyr" [109] "png" "praise" "ProtGenerics" [112] "R6" "rappdirs" "RColorBrewer" [115] "Rcpp" "RCurl" "registry" [118] "reshape2" "rex" "rjson" [121] "RJSONIO" "rlang" "rmarkdown" [124] "RMySQL" "rngtools" "roxygen2" [127] "rpart" "rprojroot" "Rsamtools" [130] "RSelenium" "RSQLite" "rstudioapi" [133] "rtracklayer" "S4Vectors" "scales" [136] "semver" "shiny" "shinyjs" [139] "snow" "sourcetools" "stringdist" [142] "stringi" "stringr" "subprocess" [145] "SummarizedExperiment" "survival" "switchr" [148] "testthat" "tibble" "trackViewer" [151] "VariantAnnotation" "viridis" "viridisLite" [154] "wdman" "whisker" "withr" [157] "XML" "xml2" "xtable" [160] "XVector" "yaml" "zlibbioc" > list.files("/usr/local/lib/R/library") [1] "base" "compiler" "datasets" "graphics" "grDevices" "grid" [7] "methods" "parallel" "splines" "stats" "stats4" "tcltk" [13] "tools" "translations" "utils" 

那么我在做什么错了？

这是我的docker-compose-yml ：
