func (*Context) ExpandEnv

func (c *Context) ExpandEnv(s string) string

ExpandEnv replaces ${var} or $var in the string according to the values of the current environment variables. References to undefined variables are replaced by the empty string.

func (*Context) Getenv

func (c *Context) Getenv(key string) string

Getenv retrieves the value of the environment variable named by the key. It returns the value, which will be empty if the variable is not present. To distinguish between an empty value and an unset value, use LookupEnv.

func (*Context) Getwd

func (c *Context) Getwd() string

Getwd returns a rooted path name corresponding to the current directory.

func (*Context) LookPath

func (c *Context) LookPath(file string) (string, bool)

This is a simplified exec.LookPath that checks if command is accessible given a PATH environment variable.

func (*Context) LookupEnv

func (c *Context) LookupEnv(key string) (string, bool)

LookupEnv retrieves the value of the environment variable named by the key. If the variable is present in the environment the value (which may be empty) is returned and the boolean is true. Otherwise the returned value will be empty and the boolean will be false.

func (*Context) SetSensitiveValues

func (c *Context) SetSensitiveValues(vals []string)

SetSensitiveValues sets the sensitive values needing masking on output/err streams WARNING: This does not work if you are writing to the TraceLogger. See https://github.com/getporter/porter/issues/2256 Only use this when you are calling fmt.Fprintln, not log.Debug, etc.

func (*Context) Setenv

func (c *Context) Setenv(key string, value string)

Setenv sets the value of the environment variable named by the key. It returns an error, if any.

func (*Context) StartRootSpan

func (c *Context) StartRootSpan(ctx context.Context, op string, attrs ...attribute.KeyValue) (context.Context, tracing.RootTraceLogger)

StartRootSpan creates the root tracing span for the porter application. This should only be done once.
