Script does not run correctly when executed from cron

i have a problem with a script, when is executed from cron the script does not work as expected but when i execute it from ssh it runs as is supposed.

Setup: QNAP NAS

The script that i'm trying to run:

#!/bin/sh
log="/share/CACHEDEV1_DATA/Jobs/logs/"
currentDate=$(date +"%m-%d-%Y")
logFile=$log"SSLCertNextCloud_"$currentDate".log"
certSource="/etc/stunnel/"
certFile="backup.cert"
certKey="backup.key"
nextCloudCert="/etc/apache2/ssl/SSLcertificate.crt"
nextCloudKey="/etc/apache2/ssl/SSLprivatekey.key"
nextCloudSSLFolder="/etc/apache2/ssl/"
containerName="NextCloudServer"

if [ "$( sudo docker container inspect -f '{{.State.Status}}' $containerName )" == "running" ]
    then
        echo $(date +"%m-%d-%Y_%T") $containerName "is up and running" >> $logFile
    else
        echo $(date +"%m-%d-%Y_%T") $containerName "is not running, trying to start" >> $logFile
        docker start $containerName
        sleep 20
        status=$( sudo docker container inspect -f '{{.State.Status}}' $containerName )
        echo $(date +"%m-%d-%Y_%T") "Status:"$status >> $logFile
        if [ $status == "running" ]
            then 
                echo $(date +"%m-%d-%Y_%T") $containerName "started successfully" >> $logFile
            else 
                echo $(date +"%m-%d-%Y_%T") "Could not start " $containerName >> $logFile
        fi
fi 

if [ ! -f $logFile ]
then
    touch $logFile
fi

if true | openssl s_client -connect myserver 2>/dev/null | \
  openssl x509 -noout -checkend 0; 
  then
    echo $(date +"%m-%d-%Y_%T") "Certificate is not expired, exiting" >> $logFile
  else
    echo $(date +"%m-%d-%Y_%T") "Certificate is expired, copying new certificate" >> $logFile
    docker cp $certSource$certFile $containerName:$nextCloudCert
    docker cp $certSource$certKey $containerName:$nextCloudKey
    echo $(date +"%m-%d-%Y_%T") "Certificates where copied, restarting server" >> $logFile
    docker restart $containerName
fi

The problem is when the script is executed from cron i get the following output:

03-25-2021_21:00:00 NextCloudServer is not running, trying to start
03-25-2021_21:00:20 Status:
03-25-2021_21:00:20 Could not start  NextCloudServer
03-25-2021_21:00:20 Certificate is not expired, exiting

It seems that it does not get a status, if i connect via SSH to the NAS and run that script, it works as designed

03-23-2021_00:00:01 NextCloudServer is up and running 03-23-2021_00:00:01 Certificate is not expired, exiting

The fix to my issue was to set the full path to docker. e.g:

docker=/share/CACHEDEV5_DATA/.qpkg/container-station/usr/bin/docker
if [ "$( $docker container inspect -f '{{.State.Status}}' $containerName )" == "running" ]
