Parameters
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.
Ports (-p)
Parameter
Function
3000
Firefox desktop gui.
Environment Variables (-e)
Env
Function
PUID=1000
for UserID - see below for explanation
PGID=1000
for GroupID - see below for explanation
TZ=Europe/London
Specify a timezone to use EG Europe/London.
Volume Mappings (-v)
Volume
Function
/config
Users home directory in the container, stores local files and settings
Miscellaneous Options
Parameter
Function
--shm-size=
This is needed for any modern website to function like youtube.
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__.
As an example:
1
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Copied!
Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.
Umask for running applications
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.
User / Group Identifiers
When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000 and PGID=1000, to find yours use id user as below:
1
  $ id username
2
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
Copied!
