I want to create a kubernetes config map with multi-lines, such as this kind of yaml:
apiVersion: v1
kind: ConfigMap
metadata:
name: nifi-bootstrap
data:
run.sh: |-
echo "Waiting to run nslookup..."
sleep 30How should I write it in a part function in my prototype?
parts:: {
bootstrap(p):: {
apiVersion: 'v1',
kind: 'ConfigMap',
metadata: {
name: p.name + '-bootstrap',
labels: {
app: p.app,
release: p.release,
},
},
data: {
'run.sh': "|-
line 1
line 2
line 3
"
but it generates yaml like this: (ks show default):
apiVersion: v1
data:
run.sh: "|-\nline 1 \nline 2\nline 3\n"
kind: ConfigMapI want to mount this config map and run it as script, but I doubt this output can work. Any idea on how to generate multi-line value in ksonnet/jsonnet?
The jsonnet "equivalent" of yaml's | is the ||| construct (see https://jsonnet.org/ref/spec.html), applied your example:
$ cat foo.jsonnet
{
parts:: {
bootstrap(p):: {
apiVersion: "v1",
kind: "ConfigMap",
metadata: {
name: p.name + "-bootstrap",
labels: {
app: p.app,
release: p.release,
},
},
data: {
"run.sh": |||
line 1
line 2
line 3
|||,
},
},
},
} {
foo: self.parts.bootstrap({name: "foo", app: "bar", release: "v1"}),
}
$ jsonnet foo.jsonnet
{
"foo": {
"apiVersion": "v1",
"data": {
"run.sh": "line 1\nline 2\nline 3\n"
},
"kind": "ConfigMap",
"metadata": {
"labels": {
"app": "bar",
"release": "v1"
},
"name": "foo-bootstrap"
}
}
}
$ jsonnet foo.jsonnet|jq -r '.foo.data["run.sh"]'
line 1
line 2
line 3
