docker - 在docker中创建/tmp目录

Question

我有以下运行node.js应用程序的Docker文件

#!/usr/bin/bash
set -e

TYPE=$1
REPO_URL=https://api.github.com/repos/nkhine/domain/tarball/$2
APP=web-$TYPE
APPENV=/ccc/$APP.env
ls $APPENV > /dev/null
echo using $APPENV

source /ccc/build.env

BUILDID=`date +%Y%m%d.%H%M%S`
BUILDDIR=/ccc/build/$APP-$BUILDID
CACHEDIR=/ccc/build/cache
CACHEFILE=$CACHEDIR/$APP.tar.gz
mkdir -p $BUILDDIR
mkdir -p $CACHEDIR

echo [== downloading $REPO_URL to $BUILDDIR ==]
cd $BUILDDIR
curl -H "Authorization: token $GITHUB_TOKEN" -L $REPO_URL | tar --extract --gzip
cd *

echo [== building docker on `pwd` ==]
IMAGE=$APP:$BUILDID
CONTAINER=$APP
cp $CACHEFILE cache.tar.gz || true
basename `pwd` > git_commit_id

docker build -t $IMAGE .
cd /ccc
rm -Rf $BUILDDIR
docker run --rm $IMAGE cat cache.tar.gz > $CACHEFILE

echo [== restarting docker ==]
docker stop $APP || true
docker rm $APP || true
docker run -d --restart always --name $APP \
    -v /tmp:/ccc/tmp \
    --link euvat:euvat \
    --link freegeoip:freegeoip \
    --link redis-$TYPE:redis \
    --link mongo-$TYPE:mongo \
    --env VIRTUAL_HOST=$TYPE.domain.tld \
    --env-file $APPENV \
    $IMAGE

echo [== tailing docker logs press [Ctrl + C] to cancel ==]
docker logs --tail=100 -f $APP

但是当我检查/ccc/tmp尚未加载到/tmp的容器中时

khine@arawaak ~ $ docker inspect web-dev

任何建议都值得赞赏，我的用例是我正在使用phantomjs创建PDF文件，然后将其通过电子邮件发送给客户端。

你有倒退的选择。您应该使用:

-v /ccc/tmp:/tmp

Mount a host directory as a data volume
