Report: failed to read from json (Docker)

[xpfgsyb]

Hi,
if I run the current Docker container with the report parameter I always get this message: time="Jan 15 01:38:55" level=error msg="Failed to read from JSON: Stdin is invalid: ". No other output is created and no mail is sent.

Environment
vuls v0.2.0 8e77937 (Docker-Image, Tag latest, Image ID af4a684f4a87)
Docker version 1.12.6, build 78d1802
Server: Debian 8.6
Command: docker run --rm -v /home/service/vuls-data/ssh:/root/.ssh:ro -v /home/service/vuls-data/data/:/vuls -v /home/service/vuls-data/log/vuls/:/var/log/vuls -v /etc/localtime:/etc/localtime:ro vuls/vuls report -cvedb-path=/vuls/cve.sqlite3 -format-short-text -config=/vuls/config.toml -to-email -debug

The results directory is located directly within the mapped data directory. Have I missed something at the update to 0.2 or is this a bug?

@xpfgsyb Thanks. I will check the issue.

I've seen the same issue but on a normal ubuntu server. I run the report command via a bash script. It works when I run the script. But I get the same error message as above when I run it via crontab.

crontab -e
56 14 * * 1-5 /home/username/vuls/run_vuls._report.sh

cat /home/username/vuls/run_vuls_report.sh

#!/bin/sh

/bin/vuls report -config=/home/username/vuls/config.toml -cvedb-path=/home/username/vuls/go-cve-dictionary/cve.sqlite3 -results-dir=/home/username/vuls/results/ -format-one-line-text -format-full-text -debug > /tmp/hello.txt

• /tmp/hello.txt is empty after cronjob
• not empty after running with ./home/username/vuls/run_vuls._report.sh

I'm also suffering from the same issue since last wednesday.
Error occurs only when cron is executed. There is no problem with command execution.

time="Jan19 17:01:01" level=error msg="Failed to read from JSON: Stdin is invalid:`

The -it flag is required

docker run --rm -it ...

@kotakanbe
Thanks! Works Well with Update line on CentOS/RHEL6

Thank you @kotakanbe, the -it flag did the trick :)

@kotakanbe I tried it with the -pipe command but couldn't get it to work, did you test it, if so how does your script / crontab look?

thanks a lot

@Klar
The -pipe option is not required for crontab.
