-### DOCKER PARAMETERS
-# Docker is the default machine implementation within Che. Workspaces are powered by machines
-# that are constructed when the workspace is started. The images used to generate containers
-# for the machines can come from DockerHub or a private Docker registry.
-che.docker.registry=${CHE_REGISTRY_HOST}:5000
-
-# If this is true, then we always pull an image from a registry even if we have an image cached
-# locally. If false, Docker only pulls image if it does not exist locally.
-che.docker.always_pull_image=true
-
-# If true, then launches all workspace runtime containers with Docker's
-# privileged mode. Please use responsibly. This is required if you want Che workspaces
-# to be able to launch their own runtimes which are embedded Docker containers.
-che.docker.privileged=false
-
-# This parameter allows to specify custom security options for the created docker container.
-# seccomp:unconfined is the default for kubernetes, but not for docker. This is needed
-# for debugging with gdbserver. See https://github.com/eclipse/che/issues/4284 for details.
-# Parameters are passed as an array, so you can add multiple 
-# values comma seperated. Please also see https://docs.docker.com/engine/api/v1.21/#2-endpoints,
-# in particular the "HostConfig":{"SecurityOpt": []} entry. If this parameter is empty,
-# docker blocks certain Syscalls by default https://docs.docker.com/engine/security/seccomp/
-# WARNING: if you give incorrect values, docker gives an error and doesn't start the container
-# Example: che.docker.securityopt=seccomp:unconfined,apparmor:unconfined
-che.docker.securityopt=
-
-# Limits the number of processes that can be forked inside a cgroup. Set -1 for unlimited.
-# Since 4.3 kernel.
-che.docker.pids_limit=-1
-
-# Sets parent cgroup for cgroups of containers created by workspaces.
-# This allows an admin to set custom cgroup limitations to all containers of workspaces by configuring cgroups.
-# Example:
-# /my_group
-# my_another_group
-che.docker.parent_cgroup=NULL
-
-# Sets set of CPUs that can be used by each container of started workspace.
-# Example:
-# 0-3
-# 1,4
-che.docker.cpuset_cpus=NULL
-
-# Next 2 properties set limits on CPU consumption by containers of started workspaces.
-# Period sets amount of units per CPU core.
-# Quota sets amount of units available for container per whole CPU.
-# Max value of quota could be period * number of CPU cores in a system.
-# Example:
-# che.docker.cpu_period=5000
-# che.docker.cpu_quota=10000
-che.docker.cpu_period=0

-
-# If the browser clients that are accessing Che are remote AND the configuration of Docker is an
-# internal IP address or using Unix sockets, then remote browser clients will not be able to connect
-# to the workspace. Set the Docker configuration so that Docker containers have an external IP
-# address and provide that external host or IP address here.
-# This is uncommon, and only needed for advanced Docker configurations.
-che.docker.ip=NULL
-
-# The hostname that a browser should use to connect to a workspace container.
-# Only set this if your workspace containers are not directly pingable.
-# This is unusual, but happens for example in Docker for Mac when containers are in a VM.

-### Che docker infrastructure parameters
-
-# This is the API endpoint of the workspace master running within the core Che server.

-# Time (in minutes) given for bootstrapping.
-# If boostrapping is not finished in time it will be failed and workspace start will fail.

-# If installation is not finished in time it will be interrupted.

-
-# URL rewriter. May be overriden in case of single-port mode e.t.c

-# Projects, which are stored in directories named after their workspace name,
-# will be stored by workspace id instead.

 ### INTERNAL

-# For debugging - set to retrieve internal events from external clients.

 # Che extensions can be scheduled executions on a time basis.
