crontab 无法使用 docker 命令运行 shell 脚本？

Question

I have a simple shell script to run a docker command below, which works just fine if I ran it manually. However it didn't work if I ran it by cron. I didn't see any logging in /var/log/cron .. And I tested cron by creating a simple script to touch a file, and it worked fine. Cron doesn't work with docker?

cat start.sh
#!/bin/bash
docker run --shm-size 2g --rm --net sitespeedio_default \
    -v "$(pwd):/sitespeed.io" sitespeedio/sitespeed.io:24.6.0\
    --pageCompleteWaitTime 30000 \
    lex-login.js lex-view_call_call_only.js -n 1 \
    --influxdb.host influxdb \
    --influxdb.username $INFLUX_U \
    --influxdb.password $INFLUX_P --spa --multi

crontab -l
2 * * * * /home/ec2-user/start.sh >/dev/null 2>&1

Answer 1

Update the crontab content to:

2 * * * *  /bin/bash /home/ec2-user/start.sh >/dev/null 2>&1

And then, make sure that the crontab 's user has the permission to run this script.
