Missing error logs on startup crash

[arne-fuchs]

I am trying to run openldap in a docker compose env. which crashes at startup without any info (running self build dev branch)

I have following docker-compose.yml config:

services:Watch   d Detach
  openldap:
    image: osixia/openldap
    container_name: openldap
    hostname: example.com
    ports:
      - "389:3890"
      - "636:6360"
    environment:
      - OPENLDAP_BOOTSTRAP_ORGANIZATION=MyExampleCompany
      - OPENLDAP_BOOTSTRAP_SUFFIX="dc=example,dc=com"
      - OPENLDAP_CONF_DIR=/config
      - OPENLDAP_DATA_DIR=/data
      - OPENLDAP_BACKUP_DIR=/backups
    volumes:
      - ./config:/config
      - ./data:/data
      - ./backups:/backups

This is the output:

Hi,

Thanks for testing the dev branch.

Could you please rerun the container with a higher log level and share the full output? The current log only shows that the bootstrap script exits with status 1, but not the underlying OpenLDAP/bootstrap error.

Also, please keep in mind that the dev branch is currently a full rewrite for v2 and is not expected to be stable yet. Opening issues against it at this stage may create unnecessary noise.

Thanks.

[arne-fuchs]

Thanks for the fast response.
I've tried setting OPENLDAP_DEBUG_LEVEL but there is no difference in the output.

[BertrandGouny]

Thanks for the feedback.

OPENLDAP_DEBUG_LEVEL only affects OpenLDAP (slapd) internal logging. It does not increase the container or startup/runtime logs.

If you want more verbose output from the container itself, you should use the baseimage flag --log-level, for example:

--log-level debug

The README has been updated to clarify this.

You can modify your docker-compose.yml like this:

openldap:
image: osixia/openldap
container_name: openldap
hostname: example.com
command: ["--log-level", "debug"]
ports:
- "389:3890"
- "636:6360"
environment:
- OPENLDAP_BOOTSTRAP_ORGANIZATION=MyExampleCompany
- OPENLDAP_BOOTSTRAP_SUFFIX="dc=example,dc=com"
- OPENLDAP_CONF_DIR=/config
- OPENLDAP_DATA_DIR=/data
- OPENLDAP_BACKUP_DIR=/backups
volumes:
- ./config:/config
- ./data:/data

This should give you much more insight into what’s happening during startup.

Frist bug if the container not have a permission
I have same error.
Cause : the user 911 have not access to mounted folder.
Solution :

chown -R 911:911 ./config
chown -R 911:911 ./data

[maitreyorene]

Second bug is OPENLDAP_BOOTSTRAP_SUFFIX="dc=example,dc=com" the script keep quote you

/container/services/openldap-bootstrap/assets/ldif/config/base/60-database.ldif.template:7:olcRootDN: ${OPENLDAP_BOOTSTRAP_DATA_ROOT_DN}
/container/services/openldap-bootstrap/assets/ldif/config/base/50-config.ldif.template:4:olcRootDN: ${OPENLDAP_BOOTSTRAP_CONFIG_ROOT_DN}
/container/services/openldap-bootstrap/assets/ldif/config/base/50-config.ldif:4:olcRootDN: cn=admin,cn=config
/container/services/openldap-bootstrap/assets/ldif/config/base/60-database.ldif:7:olcRootDN: cn=admin,"dc=example,dc=com"

Currently, the solution is to remove the double quote.

So true. Got Codex to build the whole thing for me ~6 months back. Got tired of waiting for Osixia to fix their CVE laden docker container.
