check if docker container is running before removing or deleting it via script
问题
我有一个部署名为enhanced-app的应用程序的Bash脚本。预期在构建新镜像之前首先清理所有正在运行的容器。我的当前代码已经实现了这一点，但在容器不存在或未运行的情况下，我会收到错误消息。
我希望只在enhanced-app正在运行时运行清理命令。请问如何实现这一点？
#!/bin/bash
echo "Stopping App2..."
docker container stop enhanced-app
docker container rm enhanced-app
CURPATH=$(dirname "${BASH_SOURCE[0]}")
docker build . -t enhanced-app
docker run -d -p 5000:5000 --name enhanced-app enhanced-app
英文:
I have a bash script that deploys an application called enhanced-app. It is expected to clean up all running containers first before building a new image. My current code does that, but in cases where the container doesn't exist or isn't running, I get an error.
I want to only run the cleanup command if enhanced-app is running. Please how can I achieve this?
!/bin/bash
echo "Stopping App2..."
docker container stop enhanced-app
docker container rm enhanced-app
CURPATH=$(dirname "${BASH_SOURCE[0]}")
docker build . -t enhanced-app
docker run -d -p 5000:5000 --name enhanced-app enhanced-app

以下是代码部分的翻译：
#!/bin/bash
IS_RUNNING=$(docker ps --filter name=enhanced-app --format '{{.ID}}')
if [ -n "${IS_RUNNING}" ]; then
echo "enhanced-app is running. Stopping App2 and removing container..."
docker container stop enhanced-app
docker container rm enhanced-app
else
IS_STOPPED=$(docker ps -a --filter name=enhanced-app --format '{{.ID}}')
if [ -n "${IS_STOPPED}" ]; then
echo "enhanced-app is stopped. Removing container..."
docker container rm enhanced-app
else
fi
CURPATH=$(dirname "${BASH_SOURCE[0]}")
docker build . -t enhanced-app
docker run -d -p 5000:5000 --name enhanced-app enhanced-app
英文:
I believe you can use the output of docker ps for that:
#!/bin/bash
IS_RUNNING=$(docker ps --filter name=enhanced-app --format '{{.ID}}')
if [ -n "${IS_RUNNING}" ]; then
echo "enhanced-app is running. Stopping App2 and removing container..."
docker container stop enhanced-app
docker container rm enhanced-app
else
IS_STOPPED=$(docker ps -a --filter name=enhanced-app --format '{{.ID}}')
if [ -n "${IS_STOPPED}" ]; then
echo "enhanced-app is stopped. Removing container..."
docker container rm enhanced-app
else
fi
CURPATH=$(dirname "${BASH_SOURCE[0]}")
docker build . -t enhanced-app
docker run -d -p 5000:5000 --name enhanced-app enhanced-app

你可以使用 docker container inspect 的退出状态。
if docker inspect -f '容器存在并且状态为{{.State.Status}}' enhanced-app; then
docker container stop enhanced-app
docker container rm enhanced-app
fi
英文:
You can use the exit status for docker container inspect
if docker inspect -f 'Container exists and is {{.State.Status}}' enhanced-app; then
docker container stop enhanced-app
docker container rm enhanced-app
fi
