1. After changing the container’s base image, the container fails to start when the Rancher environment variable CHANNEL_PUB_API_CFG_MIGRATE=true is set. Error: PHP Core Warning ‘yii\base\ErrorException’ with message ‘Module ‘gd’ already loaded’. See Figure 1.
chmod 0755 yii
chmod 0755 yii_test

2. When the Rancher environment variable CHANNEL_PUB_API_CFG_MIGRATE=false is set, the container starts successfully. See Figure 2.

3. When the Rancher environment variable CHANNEL_PUB_API_CFG_MIGRATE=true is set, it essentially executes a series of command-line commands.
env | grep CHANNEL_PUB_API_CFG_MIGRATE || export CHANNEL_PUB_API_CFG_MIGRATE="false"
if [[ $CHANNEL_PUB_API_CFG_MIGRATE == "true" ]]
then
php /mcloud/www/ccp_api/yii migrate --migrationPath=@yii/log/migrations/ --interactive=0
php /mcloud/www/ccp_api/yii migrate --interactive=0
php /mcloud/www/ccp_api/yii cache/flush-schema db --interactive=0

elif [[ $CHANNEL_PUB_API_CFG_MIGRATE == "false" ]]
then
echo "running without db migrate"
else
echo "please set environment variable CHANNEL_PUB_API_CFG_MIGRATE true or false"
fi
4. I decided to manually execute the above commands in the successfully started container first to determine exactly which command caused the error. I set the Rancher environment variable CHANNEL_PUB_API_CFG_MIGRATE=false. I executed the first 3 commands in sequence, and all of them threw errors. See Figure 3.

5. I searched my tech blog for: Module ‘gd’ already loaded. I had solved a similar issue before. Reference URL: https://www.shuijingwanwq.com/2020/06/15/4240/
6. I checked if gd exists in /usr/local/php/etc/php.ini. It does. See Figure 4.
;extension = "memcached.so"
extension = "redis.so"
;extension = "mongo.so"
extension = "sockets.so"
extension = "swoole.so"
extension = "mongodb.so"
extension = "rdkafka.so"
extension = "exif.so"
extension = "imagick.so"
extension = "gd.so"
extension=mcrypt.so
7. I ultimately resolved this issue by adding the following to the Dockerfile: sed -i ‘/gd.so/d’ /usr/local/php/etc/php.ini && \.
RUN sed -i 's/open_basedir = .\/:\/tmp:\/data:\/webtv/;open_basedir = .\/:\/tmp:\/data:\/webtv:\/usr\/local\/php/g' /usr/local/php/etc/php.ini && \
sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
sed -i 's/disable_functions = exec,system,passthru,shell_exec,escapeshellarg,escapeshellcmd,proc_close,proc_open,dl,popen,show/disable_functions = system,shell_exec,escapeshellarg,escapeshellcmd,dl,popen,show/g' /usr/local/php/etc/php.ini && \
sed -i 's/;realpath_cache_ttl = 120/realpath_cache_ttl = 1200/g' /usr/local/php/etc/php.ini && \
sed -i '/gd.so/d' /usr/local/php/etc/php.ini && \
sed -i 's/memory_limit = 2048M/memory_limit = 6144M/g' /usr/local/php/etc/php.ini && \
sed -i 's/pm.max_children = 20/pm.max_children = 40/g' /usr/local/php/etc/php-fpm.conf
8. After the upgrade, I ran the relevant commands again. Error: PHP Core Warning ‘yii\base\ErrorException’ with message ‘Module ‘exif’ already loaded’. I applied the same fix by adding the following to the Dockerfile: sed -i ‘/exif.so/d’ /usr/local/php/etc/php.ini && \.
9. The next extension to throw an error in sequence was sockets. I handled it the same way. A total of 3 lines of configuration were ultimately added to the Dockerfile. See Figure 5.
10. When the Rancher environment variable CHANNEL_PUB_API_CFG_MIGRATE=true is set, the container starts successfully. See Figure 6.
chmod 0755 yii
chmod 0755 yii_test
... initialization completed.
