Question

如果新创建了我的自动缩放实例，则会出现此错误。

Exited with error code 1

这是.ebextensions/crons.config中的脚本：

container_commands:
  01_cronjobs:
    command: dos2unix scripts/wp-cron.sh && su -s /bin/bash -c "scripts/wp-cron.sh" webapp
    leader_only: true

这是scripts/wp-cron.sh背后的脚本。

#!/bin/bash

# BACKUP EXISTING CRONTAB
crontab -l > /tmp/cronjob

# REMOVE EXISTING CUSTOM JOBS TO AVOID DUPLICATES
cat /tmp/cronjob | grep -v "/wp-cron.php" > /tmp/cronjob

# NEW CRONJOB RULES
echo "*/5 * * * * /usr/bin/php -f /var/app/current/wp-cron.php > /dev/null 2>&1" >> /tmp/cronjob

crontab /tmp/cronjob
rm /tmp/cronjob
echo 'Script successfully executed, crontab updated.'

webapp用户是否可能不存在？但我认为container_commands仅在应用程序准备好后执行？

这是日志文件的结尾。

那就是脚本。

    container_commands:
      01_clear_cronjobs:
        command: "rm /etc/cron.d/app_jobs > /dev/null 2>&1 || exit 0"
      02_add_cronjobs:
        command: "whoamid && cat .ebextensions/cronjobs.txt && cat .ebextensions/cronjobs.txt > /etc/cron.d/app_jobs && chmod 644 /etc/cron.d/app_jobs"
        leader_only: true

有些时候它有效，有些时候（重新创建没有）。我认为它是＆＃34;测试＆＃34;哪个失败了？或者是only_leader选项有问题吗？

我想知道为什么＆＃34; whoami＆＃34;不写日志中的东西。在工作场景中他们做到了......

Answer 1

正如您在日志开头看到的那样，您会看到第chown -R webapp:webapp /var/app/ondeck行。

这意味着webapp用户确实存在。为什么你认为这是容器命令失败的原因？您需要向容器命令添加更多日志记录，以便进行调试。

Elastic Beanstalk＆＃34; webapp＆＃34;容器命令期间不存在或错误原因？
