This is the official ANS command-line client, allowing for querying and controlling supported ANS services.
The client utilises ANS APIs to provide access to most service features. You should refer to the Getting Started section of the API documentation before proceeding below.
The CLI is distributed as a single binary, and is available for Windows, Linux and Mac. This binary
should be downloaded and placed into a directory included in your PATH. This would typically
be /usr/local/bin on most Linux distributions
Pre-compiled binaries are available at Releases
Install the dependencies, golang and make, then build from the Makefile.
# make
To copy to /usr/local/bin, as root or using sudo
# make install
To get started, we will define a single environment variable to store our API key:
Bash:
export ANS_API_KEY="iqmxgom0kairfnxzcopte5hx"
PowerShell:
$env:ANS_API_KEY="iqmxgom0kairfnxzcopte5hx"
And away we go!

The CLI utilises the common config from the underlying SDK, with details available here.
The CLI adds the following to the config schema:
api_debug: (bool) Specifies for debug messages to be output to stderrapi_pagination_perpage(int) Specifies the per-page for paginated requests
Contexts can be defined in the config file to allow for different sets of configuration to be defined. The current context can be overridden with the --context flag
The configuration file can be manipulated using the config subcommand, for example:
> ans config context update --current --api-key test1
> ans config context update someothercontext --api-key test1
> ans config context switch someothercontext
The output of all commands is determined by a single global flag --output / -o.
In addition to output, there are several output modifier flags which are explained below.
The default output format can be set in the configuration file using the output.default field, e.g.
output:
default: jsonThe default output format for the CLI is Table, which will be used when the value of the --output flag
is table or unspecified:
> ans safedns zone record list example.co.uk

The Property Modifier is available for this format
The table output style can be customised using the output.table.style field in your configuration file. This directive accepts either ascii (default) or unicode, which will change the table output to use unicode characters for borders and lines.
output:
table:
style: unicodeResults can be output as a list using the list format:
> ans safedns zone record show example.co.uk 3337874 --output list
id : 3337874
name : test.example.co.uk
type : A
content : 1.2.3.4
updated_at : 2019-03-19T16:33:55+00:00
priority : 0
ttl : 0
The Property Modifier is available for this format
Results can be output in JSON using the json format:
> ans safedns zone record show example.co.uk 3337874 --output json
[{"id":3337874,"template_id":0,"name":"test.example.co.uk","type":"A","content":"1.2.3.4","updated_at":"2019-03-19T16:33:55+00:00","ttl":0,"priority":0}]
You can also the use the json-pretty format to output pretty-printed JSON:
> ans safedns zone record show example.co.uk 3337874 --output json-pretty
[
{
"id": 3337874,
"template_id": 0,
"name": "test.example.co.uk",
"type": "A",
"content": "1.2.3.4",
"updated_at": "2019-03-19T16:33:55+00:00",
"ttl": 0,
"priority": 0
}
]
Results can be output in YAML using the yaml format:
> ans safedns zone record show example.co.uk 3337874 --output yaml
- id: 3337874
templateid: 0
name: test.example.co.uk
type: A
content: 1.2.3.4
updatedat: "2019-03-19T16:33:55+00:00"
ttl: 0
priority: 0
Results can be output with a value or set of values using the value format:
> ans safedns zone record show example.co.uk 3337874 --output value
3337874 test.example.co.uk A 1.2.3.4 2019-03-19T16:33:55+00:00 0 0
> ans safedns zone record show example.co.uk 3337874 --output value --property id
3337874
The Property Modifier is available for this format
Results can be output as CSV using the csv format:
> ans safedns zone record show example.co.uk 3337874 --output csv
id,name,type,content,updated_at,priority,ttl
3337874,test.example.co.uk,A,1.2.3.4,2019-03-19T16:33:55+00:00,0,0
The Property Modifier is available for this format
Results can be output using a supplied Golang template string using the template format
in conjunction with output arguments, e.g.
> ans safedns zone record list example.co.uk --output template="Record name: {{ .Name }}, Type: {{ .Type }}"
Record name: ns0.ans.uk, Type: NS
Record name: ns1.ans.uk, Type: NS
Record name: example.co.uk, Type: SOA
Record name: test.example.co.uk, Type: A
Results can be output via JSON Path using the jsonpath format
in conjunction with output arguments, e.g.
> ans safedns zone record list example.co.uk --output jsonpath="{[*].name}"
example.co.uk example.co.uk example.co.uk test.example.co.uk
Some output formats support the --property output modifier.
Required properties can be specified with the --property format modifer flag:
> ans safedns zone record show example.co.uk 3337874 --output value --property name
test.example.co.uk
The property modifier accepts a comma-delimited list of property names, and is also repeatable:
> ans safedns zone record show example.co.uk 3337874 --output value --property id,name --property content
3337874 test.example.co.uk 1.2.3.4
The property modifier also accepts globbing e.g. *, some*, *thing
When using list commands, filtering is available via the --filter flag. Additionally, optional operators are available.
--filter id=123
--filter id:lt=10
Additionally, the lk filter is inferred when a glob * is included in the filter value (when operator is omitted)
When using list commands, sorting is available via the --sort flag.
--sort id
--sort id:desc
The CLI has self-update functionality, which can be invoked via the command update:
> ans update
This command in-place updates the CLI, with the old binary moved to ans.old (ans.old.exe on Windows), should roll-back be required.
If you are upgrading from the old ukfast client, you will need to install this client from scratch. You will need to rename ~/.ukfast.yml to ~/.ans.yml and ensure any environment variables are updated to use the new ANS_ prefix, e.g. UKF_ECLOUD_VPC=true becomes ANS_ECLOUD_VPC=true.
The CLI supports generating shell completions for the following shells:
- Bash
- Zsh
- PowerShell
The commands at ans completion <shell: bash|zsh|powershell> provide help for installation on different platforms
goreleaser is used to release the CLI on Github.
First, we'll obtain our GPG fingerprint:
gpg -k
Next, we'll set some environment variables - including GPG fingerprint from above:
export GITHUB_TOKEN=<token>
export GPG_FINGERPRINT=<fingerprint>
export GPG_TTY=$(tty)
We'll then need to cache our GPG passphrase:
gpg --armor --detach-sign -n main.go
Finally push a new tag and invoke goreleaser:
git tag v1.10.0
git push --tags
goreleaser --rm-dist
eCloud VPC resource commands are available by default under the ecloud subcommand.
To display only VPC commands, the following environment variable can be set:
> export ANS_ECLOUD_VPC=true
To display only original commands, the following environment variable can be set:
> export ANS_ECLOUD=true
