Error when starting httpd

[CramericaIndustries]

launch command: docker run --rm -p 5001:8080 -v /docker/awstats/awstats-db:/var/lib/awstats openmicroscopy/awstats httpd

Output:

I can't reproduce this. Are you running this as part of docker compose or some other docker orchestration tool? If so can you give us your full configuration?

[CramericaIndustries]

Yes at first I tried it with docker-compose. Then I got that 'pid-file permission denied' error message. After that I've tried it without docker-compose using above startup command with the same outcome:

root@v22015123209730424:/docker/awstats# docker run --rm -p 5001:8080 -v /docker/awstats/awstats-db:/var/lib/awstats openmicroscopy/awstats httpd

(13)Permission denied: AH00058: Error retrieving pid file /run/httpd/httpd.pid
AH00059: Remove it before continuing if it is corrupted.

When you tried to reproduce the error, did you delete your openmicroscopy/awstats image first?

My Docker Version:

root@v22015123209730424:/docker/awstats# docker -v
Docker version 17.05.0-ce, build 89658be

OS is Debian 8 x64

For testing I've started a container from your image with sleep infinity as run command. Then I've executed /bin/bash to get a console running in the container and checked out the /run/httpd directory:

bash-4.2$ cd /run/httpd/
bash-4.2$ whoami

That htcacheclean file looks a bit weird. Would it be possible that the image is corrupt?

Can you share with us what options your docker daemon is using? Also, what filesystem is being used for /var/lib/docker?

[CramericaIndustries]

How do I find out the options of the docker daemon? Do you mean the output of docker inspect <containerid>?

filesystem of the awstats container:

root@v22015123209730424:/docker/awstats# mount | grep 8a1a40d588ee
shm on /var/lib/docker/containers/8a1a40d588eeef2af2071430d5a5e61b0cb42cdecb9bfb26df3859468e998365/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=65536k)

[joshmoore]

How do I find out the options of the docker daemon?

No, more:

cat /etc/docker/daemon.json

or even just:

# ps auxw | grep -E "\sdocker-containerd\s"
root       2702  0.1  0.0 5656560 34784 ?       Ssl   2017 439:08 docker-containerd -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --shim docker-containerd-shim --runtime docker-runc

and regarding the filesystem, what does:

df -P /var/lib/docker

show?

[CramericaIndustries]

Don't have a /etc/docker/daemon.json file.

Cloned your git repository and tried to build the Dockerfile, which failed saying that it can't extract the httpd package. Then I found multiple other people having the same problem. Looks like there is a bug in AuFS which leads to problems when running CentOS docker images on Debian/Ubuntu hosts. @joshmoore thanks for your help anyways!

[joshmoore]

Glad you could track it down, @CramericaIndustries. Good luck!

[siggepop]

Hm... intressting. I run RHEL 7 and use RHEL 7 container image and have the same problem.

@siggepop : re-opening. If you find a workaround or have more details, please add them here.
