Command namespace resolves and manages names in the Vanadium namespace.
The namespace roots are set from the command line via --v23.namespace.root command line option or from environment variables that have a name starting with V23_NAMESPACE, e.g. V23_NAMESPACE, V23_NAMESPACE_2, V23_NAMESPACE_GOOGLE, etc. The command line options override the environment.
Usage:
namespace [flags] <command>
The namespace commands are:
glob Returns all matching entries from the namespace mount Adds a server to the namespace unmount Removes a server from the namespace resolve Translates a object name to its object address(es) resolvetomt Finds the address of the mounttable that holds an object name permissions Manipulates permissions on an entry in the namespace delete Deletes a name from the namespace help Display help for commands or topics
The global flags are:
-v23.namespace.root=[/(dev.v.io:r:vprod:service:mounttabled)@ns.dev.v.io:8101] local namespace root; can be repeated to provided multiple roots -alsologtostderr=true log to standard error as well as files -log_backtrace_at=:0 when logging hits line file:N, emit a stack trace -log_dir= if non-empty, write log files to this directory -logtostderr=false log to standard error instead of files -max_stack_buf_size=4292608 max size in bytes of the buffer to use for logging stack traces -metadata=<just specify -metadata to activate> Displays metadata for the program and exits. -stderrthreshold=2 logs at or above this threshold go to stderr -time=false Dump timing information to stderr before exiting the program. -v=0 log level for V logs -v23.credentials= directory to use for storing security credentials -v23.permissions.file= specify a perms file as <name>:<permsfile> -v23.permissions.literal= explicitly specify the runtime perms as a JSON-encoded access.Permissions. Overrides all --v23.permissions.file flags -v23.proxy= object name of proxy service to use to export services across network boundaries -v23.proxy.limit=0 max number of proxies to connect to when the policy is to connect to all proxies; 0 implies all proxies -v23.proxy.policy= policy for choosing from a set of available proxy instances -v23.tcp.address= address to listen on -v23.tcp.protocol= protocol to listen with -v23.virtualized.advertise-private-addresses= if set the process will also advertise its private addresses -v23.virtualized.disallow-native-fallback=false if set, a failure to detect the requested virtualization provider will result in an error, otherwise, native mode is used -v23.virtualized.dns.public-name= if set the process will use the supplied dns name (and port) without resolution for its entry in the mounttable -v23.virtualized.docker= set if the process is running in a docker container and needs to configure itself differently therein -v23.virtualized.provider= the name of the virtualization/cloud provider hosting this process if the process needs to configure itself differently therein -v23.virtualized.tcp.public-address= if set the process will use this address (resolving via dns if appropriate) for its entry in the mounttable -v23.virtualized.tcp.public-protocol= if set the process will use this protocol for its entry in the mounttable -v23.vtrace.cache-size=1024 The number of vtrace traces to store in memory -v23.vtrace.collect-regexp= Spans and annotations that match this regular expression will trigger trace collection -v23.vtrace.dump-on-shutdown=true If true, dump all stored traces on runtime shutdown -v23.vtrace.sample-rate=0 Rate (from 0.0 to 1.0) to sample vtrace traces -v23.vtrace.v=0 The verbosity level of the log messages to be captured in traces -vmodule= comma-separated list of globpattern=N settings for filename-filtered logging (without the .go suffix). E.g. foo/bar/baz.go is matched by patterns baz or *az or b* but not by bar/baz or baz.go or az or b.* -vpath= comma-separated list of regexppattern=N settings for file pathname-filtered logging (without the .go suffix). E.g. foo/bar/baz.go is matched by patterns foo/bar/baz or fo.*az or oo/ba or b.z but not by foo/bar/baz.go or fo*az
Returns all matching entries from the namespace.
Usage:
namespace glob [flags] <pattern>
<pattern> is a glob pattern that is matched against all the names below the specified mount name.
The namespace glob flags are:
-fail-on-any-error=false exit on any error, by default glob will report errors but not return a non-zero exit code -l=false Long listing format.
Adds server <server> to the namespace with name <name>.
Usage:
namespace mount [flags] <name> <server> <ttl>
<name> is the name to add to the namespace. <server> is the object address of the server to add. <ttl> is the TTL of the new entry. It is a decimal number followed by a unit suffix (s, m, h). A value of 0s represents an infinite duration.
Removes server <server> with name <name> from the namespace.
Usage:
namespace unmount [flags] <name> <server>
<name> is the name to remove from the namespace. <server> is the object address of the server to remove.
Translates a object name to its object address(es).
Usage:
namespace resolve [flags] <name>
<name> is the name to resolve.
The namespace resolve flags are:
-insecure=false Insecure mode: May return results from untrusted servers and invoke Resolve on untrusted mounttables -s=false True to perform a shallow resolution
Finds the address of the mounttable that holds an object name.
Usage:
namespace resolvetomt [flags] <name>
<name> is the name to resolve.
The namespace resolvetomt flags are:
-insecure=false Insecure mode: May return results from untrusted servers and invoke Resolve on untrusted mounttables
Commands to get and set the permissions on a name - controlling the blessing names required to resolve the name.
The permissions are provided as an JSON-encoded version of the Permissions type defined in v.io/v23/security/access/types.vdl.
Usage:
namespace permissions [flags] <command>
The namespace permissions commands are:
get Gets permissions on a mount name set Sets permissions on a mount name
Get retrieves the permissions on the usage of a name.
The output is a JSON-encoded Permissions object (defined in v.io/v23/security/access/types.vdl).
Usage:
namespace permissions get [flags] <name>
<name> is a name in the namespace.
Set replaces the permissions controlling usage of a mount name.
Usage:
namespace permissions set [flags] <name> <permissions>
<name> is the name on which permissions are to be set.
<permissions> is the path to a file containing a JSON-encoded Permissions object (defined in v.io/v23/security/access/types.vdl), or "-" for STDIN.
Deletes a name from the namespace.
Usage:
namespace delete [flags] <name>
<name> is a name to delete.
The namespace delete flags are:
-r=false Delete all children of the name in addition to the name itself.
Help with no args displays the usage of the parent command.
Help with args displays the usage of the specified sub-command or help topic.
"help ..." recursively displays help for all commands and topics.
Usage:
namespace help [flags] [command/topic ...]
[command/topic ...] optionally identifies a specific sub-command or help topic.
The namespace help flags are:
-style=compact The formatting style for help output: compact - Good for compact cmdline output. full - Good for cmdline output, shows all global flags. godoc - Good for godoc processing. shortonly - Only output short description. Override the default by setting the CMDLINE_STYLE environment variable. -width=<terminal width> Format output to this target width in runes, or unlimited if width < 0. Defaults to the terminal width if available. Override the default by setting the CMDLINE_WIDTH environment variable.
