SYNOPSIS

11       oc adm migrate storage [OPTIONS]

DESCRIPTION

16       Migrate internal object storage via update
17
18
19       This  command invokes an update operation on every API object reachable
20       by the caller. This forces the server to write to the underlying  stor‐
21       age  if  the  object  representation  has  changed. Use this command to
22       ensure that the most recent storage changes have been  applied  to  all
23       objects (storage version, storage encoding, any newer object defaults).
24
25
26       To  operate  on  a  subset of resources, use the --include flag. If you
27       encounter errors during a  run  the  command  will  output  a  list  of
28       resources  that  received errors, which you can then re-run the command
29       on. You may also specify --from-key and --to-key to restrict the set of
30       resource  names  to  operate on (key is NAMESPACE/NAME for resources in
31       namespaces or NAME for cluster scoped resources). --from-key is  inclu‐
32       sive if specified, while --to-key is exclusive.
33
34
35       By  default,  events  are  not migrated since they expire within a very
36       short period of time. If you have significantly increased  the  expira‐
37       tion time of events, run a migration with --include=events
38
39
40       WARNING: This is a slow command and will put significant load on an API
41       server. It may also result in significant intra-cluster traffic.

OPTIONS

46       --all-namespaces=true
47           Migrate objects in all namespaces. Defaults to true.
48
49
50       --allow-missing-template-keys=true
51           If true, ignore any errors in templates when a field or map key  is
52       missing  in  the  template.  Only applies to golang and jsonpath output
53       formats.
54
55
56       --bandwidth=10
57           Average network bandwidth measured in megabits per second (Mbps) to
58       use during storage migration.  Zero means no limit.  This flag is alpha
59       and may change in the future.
60
61
62       -f, --filename=[]
63           Filename, directory, or URL to docker-compose.yml file to use
64
65
66       --from-key=""
67           If specified, only migrate items  with  a  key  (namespace/name  or
68       name) greater than or equal to this value
69
70
71       --include=[*]
72           Resource  types  to  migrate. Passing --filename will override this
73       flag.

75
76       --no-headers=false
77           When using the default or custom-column output format, don't  print
78       headers (default print headers).
79
80
81       --show-labels=false
82           When  printing,  show  all  labels as the last column (default hide
83       labels column)
84
85
86       --sort-by=""
87           If non-empty, sort list types using this field specification.   The
88       field  specification  is  expressed  as  a  JSONPath  expression  (e.g.
89       '{.metadata.name}'). The field in the API resource  specified  by  this
90       JSONPath expression must be an integer or a string.
91
92
93       --template=""
94           Template  string  or  path  to template file to use when -o=go-tem‐

97
98
99       --to-key=""
100           If  specified,  only  migrate  items  with a key (namespace/name or
