有没有办法让 echo 显示在发出 docker run 命令的终端中。如果不使用 -d 选项,似乎只有在此处显示 echo。我可以做 docker logs 来查看这些回声,但我想知道是否有办法让它们直接在终端中显示运行命令?
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"]
入口点脚本:
#!/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 .
