worker job from concourse/7.8.3

The 'worker' nodes are what actually run Concourse workloads (builds, resource checking, etc). They register with Concourse via the SSH worker gateway running on the 'web' nodes.

Github source: 21e7301 or master branch

Properties¶

allow_host_access¶

Allows containers to reach host network

bin¶

Path to a containerd executable (non-absolute names get resolved from $PATH).

cni_bin¶

Enable a proxy DNS server for Garden. Note: this implicitly turns on container access to host network.

List of DNS server IP addresses to use instead of automatically determined servers.

external_ip¶

IP address to use to reach container’s mapped ports. Autodetected if not specified.

init_bin¶

Path to an init executable. For BOSH this defaults to /var/vcap/packages/concourse/bin/init when containerd is selected as the runtime.

max_containers¶

Maximum container capacity. 0 means no limit. Defaults to 250.

mtu¶

MTU size for container network interfaces. Defaults to the MTU of the interface used for outbound access by the host.

network_pool¶

Network range to use for dynamically allocated container subnets. Defaults to “10.80.0.0/16”.

request_timeout¶

Time to wait for requests to Containerd to complete. 0 means no timeout.

restricted_networks¶

List of network ranges to which traffic from containers will be restricted.

`debug`¶

bind_ip¶

IP address on which to listen for the pprof debugger endpoints.
Default
127.0.0.1
bind_port¶

Port on which to listen for the pprof debugger endpoints.
Default
7776

`drain_timeout`¶

Maximum wait time in Go duration format (1m = 1 minute) for worker drain to be finished. Only applies when worker is getting shutdown.

Default

1h

`ephemeral`¶

If set, the worker will immediately disappear upon stalling.

Default

false

`external_garden_url`¶

API endpoint of an externally managed Garden server to use instead of running the embedded Garden server.

`garden`¶

allow_host_access¶

Allow containers to reach the worker VM’s network.

config_ini¶

Contents of the Garden configuration. Use to customize the container runtime. This may over-ride any other environment variables specified. See: https://concourse-ci.org/concourse-worker.html#configuring-gdn-server

deny_networks¶

Network ranges to which traffic from containers will be denied.
Example
[]
dns_servers¶

DNS servers IP addresses to use instead of automatically propagating the host’s DNS configuration.
Example
[]
max_containers¶

Maximum container capacity to advertise. 0 means no limit. Defaults to 250.

network_pool¶

Network range to use for dynamically allocated container subnets. Defaults to “10.80.0.0/16”.

request_timeout¶

How long to wait for requests to Garden to complete, in Go duration format (48h = 48 hours). 0 means no timeout.
Example
5m

`healthcheck`¶

bind_ip¶

IP address on which to listen for health checking requests.

bind_port¶

Port on which to listen for health checking requests.

timeout¶

HTTP timeout for the full duration of health checking.

`http_proxy_url`¶

Proxy to use for outgoing http requests from containers.

`https_proxy_url`¶

Proxy to use for outgoing https requests from containers.

`log_level`¶

The log level for the worker. When set to debug, you’ll see a lot more information.

Default

info

`no_proxy`¶

A list domains and IPs with optional port for which the proxy should be bypassed.

Example

- localhost
- 127.0.0.1
- example.com
- domain.com:8080

`runtime`¶

Container runtime for worker. Possible values are “guardian”, “containerd”, and “houdini”. Please note that Houdini is insecure and does not run tasks in containers.

Example

guardian

`sweep_interval`¶

Interval on which to destroy containers and volumes marked for garbage collection.

Default

30s

`tags`¶

An array of tags to advertise for each worker.

Example

- special

Example
ssh-rsa ...
hosts¶

Addresses (host:port) of TSA servers to register with.

If not specified, the web link is used.

rebalance_interval¶

The interval on which the worker will connect to a new SSH gateway and drain the old connection. This has the effect of rebalancing the forwarded workers across the SSH gateways over time.
Example
4h
worker_key¶

SSH key to use when authenticating with the TSA.
Example
private_key: |+
  -----BEGIN RSA PRIVATE KEY-----
  ...
