Why are only some created directories showing up in the final running image. Here are my steps. It should be trivial:
Use this Dockerfile:
FROM wordpress:4.8.2-php7.0-apache RUN mkdir -pv \ /var/www/html/blog/wp-content/uploads/pb_backupbuddy \ /var/www/html/blog/wp-content/uploads/backupbuddy_temp \ /var/www/html/blog/wp-content/uploads/backupbuddy_backups \ /var/www/html/blog/wp-content/cache \ /var/app/current/public \ /var/www/html/blog && chown -R www-data:www-data /var/www/html/blog
Then build it with this command:
docker build -t stockmusic-blog:latest .
I see this output (truncated):
---> Running in 4c1a7a0b7ee3 mkdir: created directory '/var/www/html/blog' mkdir: created directory '/var/www/html/blog/wp-content' mkdir: created directory '/var/www/html/blog/wp-content/uploads' mkdir: created directory '/var/www/html/blog/wp-content/uploads/pb_backupbuddy' mkdir: created directory '/var/www/html/blog/wp-content/uploads/backupbuddy_temp' mkdir: created directory '/var/www/html/blog/wp-content/uploads/backupbuddy_backups' mkdir: created directory '/var/www/html/blog/wp-content/cache' mkdir: created directory '/var/app' mkdir: created directory '/var/app/current' mkdir: created directory '/var/app/current/public' ---> 51cf49fe0867 Removing intermediate container 4c1a7a0b7ee3 Successfully built 51cf49fe0867 Successfully tagged stockmusic-blog:latest
The output shows the directories are being created.
Okay, lets run the container and see the newly created directories:
└─> docker run -d stockmusic-blog:latest dde6311c8997c01386cbbc0174e0c30d164cc5d2188b6b04377aeb1e6b156538 └─> docker exec -t -i dde6311 /bin/bash root@dde6311c8997:/var/www/html# cd /var/app/current/public/ root@dde6311c8997:/var/app/current/public# root@dde6311c8997:/var/app/current/public# cd /var/www/html/blog/wp-content bash: cd: /var/www/html/blog/wp-content: No such file or directory root@dde6311c8997:/var/www/html# cd /var/www/html/blog bash: cd: /var/www/html/blog/: No such file or directory
So the directory
/var/app/current/public Was created successfully, but none of the other directories are there.
Why? What is going on here? I’m really pulling my hair out on this one. Thanks!
