Hi @g-vdn,

Thank you for getting in touch. I have attempted to replicate the issue, but unfortunately, I was not able to reproduce it.

I used the docker-compose.yml file and deployed wordpress-nginx:latest, and WordPress responded without any issues:

$ cd bitnami/
$ docker-compose up -d
$ curl -Is http://localhost
HTTP/1.1 200 OK
Server: nginx
...
$

Additionally, please note that you have the option to enhance the image with extra libraries by customizing it. You can refer to the customization guide at https://github.com/bitnami/containers/tree/main/bitnami/wordpress-nginx#customize-this-image for instructions on extending the image.

I hope this information assists you in resolving your issue.

Hi @fevisera,

Replying quite late, had some RAM issues which crashed the server on which container is running.

Thanks for looking into this. I am using unRAID hypervisor, it's kinda picky when you are not installing dockers from the Community Apps, I installed this image from Docker hub, manually set-up each ENV var I thought is needed, and worked fine for a while, I created a wordpress site, test it, etc. I don't work actively on it, so no idea when this issue happened exactly, but now I am stuck with this

Not very good with dockers at this point, I know just little above the basics. Seems to me that library missing from host OS, am I correct in this?

[fevisera]

Hi @g-vdn,

No problem. That library seems to be available in the latest container:

$ docker-compose -f bitnami/wordpress-nginx/6/debian-12/docker-compose.yml exec -it wordpress bash
I have no name!@95402c8e53cd:/$ ldconfig -p |grep libldap
        libldap-2.5.so.0 (libc6,x86-64) => /lib/x86_64-linux-gnu/libldap-2.5.so.0

Could you try using the latest container version (6.4.3-debian-12-r0), available a couple of days ago, and check if the error persist? If the error persists, it would be greatly appreciated if you could share the details of the container configuration (such as environment variables, configuration files, etc.) that are being set up, so that I can attempt to reproduce the issue.

Thanks!

[g-vdn]

Hi @fevisera

Here are the environment variables used:

Till now I was using latest image, now used debian one which you mentioned, same thing

What config files would you need? I have 2 persistent locations mapped, as is visible in XML. Let me know which you need and I'll share.

Thanks!

[fevisera]

Hi,

The docker images command does not reflect which image is being used by your wordpress-nginx container. Maybe you should try running docker ps which would provide information on which the docker image is being used by each container.

Regarding the config file, I'm not sure how you are providing an XML for configuring the container. Could you share more details on how you are deploying the container?

[g-vdn]

Hi @fevisera ,

I am running the container under unRAID hypervisor, running Slackware OS

Hi @g-vdn,

Could you share the exact steps to reproduce the error?

We may be missing something because the docker image includes libldap-2.5-0 library installed, so I do not get why your deployment is complaining about a previous version.

You can check that the library is there by doing the following, mentioned previously:

$ docker-compose exec -it wordpress ldconfig -p |grep libldap
        libldap-2.5.so.0 (libc6,x86-64) => /lib/x86_64-linux-gnu/libldap-2.5.so.0
$ 
$ docker-compose exec -it wordpress ls -l /lib/x86_64-linux-gnu/libldap-2.5.so.0
lrwxrwxrwx 1 root root 20 Feb  8  2023 /lib/x86_64-linux-gnu/libldap-2.5.so.0 -> libldap-2.5.so.0.1.8
$ 
$ docker-compose exec -it wordpress /opt/bitnami/php/bin/php --version

Hi @fevisera,

Figured out the issue, /opt/bitnami was mapped as persistent storage.
I remember doing this because after every docker update or restart (this was many months back), WP version reverted to what it was previously, didn't persist. After mapping /opt/bitnami locally all was fine, till it didn't work. Now I see that WP stays at current version even after docker update/reboot.
Seems image updates don't work their way into local storage, what is mapped , like /opt/bitnami , will keep old data.

Before:
-v '/mnt/user/appdata/wordpress-nginx/main':'/bitnami/wordpress/':'rw'
-v '/mnt/user/appdata/wordpress-nginx/opt':'/opt/bitnami':'rw'

After:
-v '/mnt/user/appdata/wordpress-nginx':'/bitnami/wordpress/':'rw' 'bitnami/wordpress-nginx:latest'

Thanks a lot for your assistance
