Question

我有一个部署设置，可以将next.js存储库推送到我在服务器上已设置的git remote上。

我有一个接收后挂钩设置，然后将其构建到临时文件夹中，然后再将其复制到其永久文件夹并以PM2启动。

# post-receive

#!/bin/sh

# The production directory
TARGET="/var/node-apps/my-app"

# A temporary directory for deployment
TEMP="/var/node-apps/tmp/my-app"

# The Git repo
REPO="/var/git/my-app.git"

# The Git branch
BRANCH="master"

# Deploy the content to the temporary directory
echo ‘post-receive: copy to tmp’
mkdir -p $TEMP

git --work-tree=$TEMP --git-dir=$REPO checkout $BRANCH -f
echo ‘post-receive: checkout branch’
cd $TEMP

echo ‘post-receive: npm install…’
npm install \
&& echo ‘post-receive: building…’ \
&& npm run build \
&& echo ‘post-receive: → done.’


# Replace the production directory
# with the temporary directory
cd /
rm -rf $TARGET
mv $TEMP $TARGET
cd $TARGET

(pm2 delete 'my-app' || true)
pm2 start npm --name 'my-app' -- run start-production -i max
echo ‘post-receive: app started successfully with pm2.’
pm2 save
echo ‘post-receive: pm2 saved.’

这很好用，但是，如果构建失败（例如，出现掉毛错误），则接收后脚本将继续执行，并将失败的构建复制到永久目录，并使用PM2启动应用程序（课程失败，因为构建失败）。

如果webpack构建失败，我希望接收后钩子不再继续，而是发出警告。

我试图处理类似这样的错误：

abort()
{
    echo >&2 '
***************
*** ABORTED ***
***************
'
    echo "An error occurred. Exiting..." >&2
    exit 1
}

trap 'abort' 0
trap 'abort' 1

set -e

[rest of script here]

trap : 0
trap : 1

但是这也不起作用。

通过@torek的注释提示找出了答案

我保留了中止陷阱，并将&& npm run build \更改为&& npm run build || exit 1 \。

我不确定陷阱是否绝对必要，因为如果npm run build失败，脚本将退出。

# post-receive

#!/bin/sh

abort()
{
    echo >&2 '
***************
*** ABORTED ***
***************
'
    echo "An error occurred. Exiting..." >&2
    exit 1
}

trap 'abort' 0
trap 'abort' 1

set -e


echo ‘post-receive: Triggered.’

# The production directory
TARGET="/var/node-apps/myapp"

# A temporary directory for deployment
TEMP="/var/node-apps/tmp/myapp"

# The Git repo
REPO="/var/git/myapp.git"

# The Git branch
BRANCH="master"

# Deploy the content to the temporary directory
echo ‘post-receive: copy to tmp’
mkdir -p $TEMP

git --work-tree=$TEMP --git-dir=$REPO checkout $BRANCH -f
echo ‘post-receive: checkout branch’
cd $TEMP

# Do stuffs, like npm install…
echo ‘post-receive: npm install…’
npm install \
&& echo ‘post-receive: building…’ \
&& npm run build || exit 1 \
&& echo ‘post-receive: → done.’


# Replace the production directory
# with the temporary directory
cd /
rm -rf $TARGET
mv $TEMP $TARGET
cd $TARGET

(pm2 delete 'myapp' || true)
pm2 start npm --name 'myapp' -- run start-production -i max
echo ‘post-receive: app started successfully with pm2.’
pm2 save
echo ‘post-receive: pm2 saved.’

# Done!
trap : 0
trap : 1

echo >&2 '
************
*** DONE *** 
************
'

如果Webpack构建失败，则终止接收后钩子
