Problem
You would like to access a host set up with nginx after adding your own vhost configuration file in /etc/nginx/conf.d/myfile.smth, but you get Connection refused.
Solution
Make sure that your nginx configuration file has the .conf extension as /etc/nginx/conf.d/myfile.conf.
Problem
You have a folder with many gzipped files that you want to unzip at the same time.
Solutionls -al | grep gz | awk ‘{ print $9}’ | xargs gunzip
Problem
You are trying to use docker-compose to get some services up with docker but you see an error like the following:
Cannot create container for service xxx: invalid mode: /path/to/volume/
Solution
This is more than likely caused by a typo in your yml file, so go back and check carefully for any typos and correct them.
Problem
Using docker-compose up (or build), displays the following error message (even though the same command used to work previously):
ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?
Solution
This is quite possible caused by permissions issue, as one of the folders files that docker is trying to use is owned by a different user/group from the one trying to use the docker-compose commands. Try to find the file/folder with the different permissions and change it to your user name and group, or use change the files by using something like:
chown -R me:me .
Problem
You are trying to run the ps command in a docker container (ie ps ax), but you get:
