Variables

var MustEnvVars = map[string]string{
	"PORT": "8801",
}

MustEnvVars defines environment variables that "MUST" be set. The value provided is an example value.

var MustFiles = map[string]FileInfo{
	"/dev/fd": {
		IsDir:      ptr.Bool(true),
		SourceFile: "/proc/self/fd",
	},
	"/dev/full": {
		IsDir: ptr.Bool(false),
	},
	"/dev/null": {
		IsDir: ptr.Bool(false),
	},
	"/dev/ptmx": {
		IsDir: ptr.Bool(false),
	},
	"/dev/random": {
		IsDir: ptr.Bool(false),
	},
	"/dev/stdin": {
		IsDir:      ptr.Bool(false),
		SourceFile: "/proc/self/fd/0",
	},
	"/dev/stdout": {
		IsDir:      ptr.Bool(false),
		SourceFile: "/proc/self/fd/1",
	},
	"/dev/stderr": {
		IsDir:      ptr.Bool(false),
		SourceFile: "/proc/self/fd/2",
	},
	"/dev/tty": {
		IsDir: ptr.Bool(false),
	},
	"/dev/urandom": {
		IsDir: ptr.Bool(false),
	},
	"/dev/zero": {
		IsDir: ptr.Bool(false),
	},
	"/proc/self/fd": {
		IsDir: ptr.Bool(true),
	},
	"/proc/self/fd/0": {
		IsDir: ptr.Bool(false),
	},
	"/proc/self/fd/1": {
		IsDir: ptr.Bool(false),
	},
	"/proc/self/fd/2": {
		IsDir: ptr.Bool(false),
	},
	"/tmp": {
		IsDir: ptr.Bool(true),
		Perm:  "rwxrwxrwx",
	},
	"/var/log": {
		IsDir: ptr.Bool(true),
		Perm:  "rwxrwxrwx",
	},
}

MustFiles specifies the file paths and expected permissions that MUST be set as specified in the runtime contract. See https://golang.org/pkg/os/#FileMode for "Mode" string meaning. '*' indicates no specification.

var ShouldEnvVars = map[string]string{
	"K_SERVICE":       "Service",
	"K_CONFIGURATION": "Config",
	"K_REVISION":      "Revision",
}

ShouldEnvVars defines environment variables that "SHOULD" be set. To match these values with test service parameters, map values must represent corresponding test.ResourceNames fields

var ShouldFiles = map[string]FileInfo{
	"/etc/resolv.conf": {
		IsDir: ptr.Bool(false),
		Perm:  "rw*r**r**",
	},
	"/dev/console": {
		Error: "stat /dev/console: no such file or directory",
	},
}

ShouldFiles specifies the file paths and expected permissions that SHOULD be set as specified in the runtime contract. See https://golang.org/pkg/os/#FileMode for "Mode" string meaning. '*' indicates no specification.
