Docker：用於運行Docker的終端的回顯圖像

Question

有沒有一種方法可以在發出docker run命令的終端中顯示回顯。如果沒有使用-d選項，這裏只顯示echo。我可以做碼頭日誌來查看這些回聲，但我想知道是否有方法讓他們直接在終端發出運行命令？

Dockerfile：

# Generic Docker Image for Running Node app from Git Repository 
FROM node:0.10.33-slim 
ENV NODE_ENV production 

# Add script to pull Node app from Git and run the app 
COPY docker-node-entrypoint.sh /entrypoint.sh 
RUN chmod +x /entrypoint.sh 
ENTRYPOINT ["/entrypoint.sh"] 

EXPOSE 8080 
CMD ["--help"] 

入口點腳本：

#!/bin/bash 
set -e 
# Run the command passed in if it isn't to start a node app 
if [ "$1" != 'node-server' ]; then 
    exec "$@" 
fi 
# Logic for pulling the node app and starting it 
cd /usr/src 
# try to remove the repo if it already exists 
rm -rf node-app; true 
echo "Pulling Node app's source from $2" 
git clone $2 node-app 
cd node-app 
# Check if we should be running a specific commit from the git repo 
if [ ! -z "$3" ]; then 
    echo "Changing to commit $3" 
    git checkout $3 
fi 
npm install 
echo "Starting the app" 
exec node .

你可以有兩種-d或標準輸出，但不能同時使用。如果你想在後臺運行與標準輸出的容器，你可以使用&

$ docker run ubuntu echo "Stdout from container" & 
[1] 2751 
$ Stdout from container 

或者你可以使用-d和搬運工日誌-f
