Docker¶
In case you tried to install Dashticz several times via the automatic install script, you might end in having multiple Dashticz instances in parallel. The sections below can help in cleaning up.
To see all docker containers:
sudo docker ps
This will give output similar as:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
500c42ae47eb dtv3-8083 "docker-php-entrypoi…" 3 weeks ago Up 2 weeks 0.0.0.0:8083->80/tcp dtv3-8083
af0cd4278a60 dtv3-8082 "docker-php-entrypoi…" 3 weeks ago Up 2 weeks 0.0.0.0:8082->80/tcp dtv3-8082
In this example you see there are two Dashticz containers running, on port 8082 and port 8083.
To stop the container with name dtv3-8083, which is running on port 8083:
sudo docker stop -t 5 dtv3-8083
The -t 5 parameter will give the container 5 seconds to gracefully shut down.
After this you have an unused, stopped image dtv3-8083.
To get an overview of all images:
sudo docker images
This will show something like:
REPOSITORY TAG IMAGE ID CREATED SIZE
<none> <none> a5d13a69533b 3 weeks ago 414MB
dtv3-8082 latest 5c0cc9bf78e7 3 weeks ago 414MB
dtv3-8083 latest 5c0cc9bf78e7 3 weeks ago 414MB
dtv3-8084 latest 5c0cc9bf78e7 3 weeks ago 414MB
php apache 5e1d7ed3b92a 5 weeks ago 414MB
hello-world latest fce289e99eb9 16 months ago 1.84kB
To remove all unused containers and images:
sudo docker system prune
You will see a prompt, to which you can answer Y:
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
Are you sure you want to continue? [y/N] Y

You can check the results with sudo docker ps and sudo docker images
If you want to change the port number of a running Dashticz container:
Switch to the Dashticz root folder:
cd <dashticz>
If you followed the automatic install script, there will be Makefile.ini file, with the following content:
APP=dtv3-8084
PORT=8084
To stop the current container:
make stop
Edit Makefile.ini, and change the PORT number, and APP name (the last one is not really needed, but makes life easier):
nano Makefile.ini
Then restart the container:
make start
And voila, you now have a Dashticz container running on a new port.
