6 buildah-pull - Pull an image from a registry.
7
8
10 buildah pull [options] image
11
12
14 Pulls an image based upon the specified image name. Image names use a
15 "transport":"details" format.
16
17
18 Multiple transports are supported:
19
20
21 dir:path
22 An existing local directory path containing the manifest, layer tar‐
23 balls, and signatures in individual files. This is a non-standardized
24 format, primarily useful for debugging or noninvasive image inspection.
25
26
27 docker://docker-reference (Default)
28 An image in a registry implementing the "Docker Registry HTTP API
29 V2". By default, uses the authorization state in $XDG\_RUN‐
30 TIME\_DIR/containers/auth.json, which is set using (buildah login). If
31 the authorization state is not found there, $HOME/.docker/config.json
32 is checked, which is set using (docker login).
33 If docker-reference does not include a registry name, localhost will
34 be consulted first, followed by any registries named in the registries
35 configuration.
36
37
38 docker-archive:path
39 An image is retrieved as a docker load formatted file.
40
41
42 docker-daemon:docker-reference
43 An image docker-reference stored in the docker daemon's internal
44 storage. docker-reference must include either a tag or a digest.
45 Alternatively, when reading images, the format can also be docker-dae‐
46 mon:algo:digest (an image ID).
47
48
49 oci:path:tag**
50 An image tag in a directory compliant with "Open Container Image Lay‐
51 out Specification" at path.
52
53
54 oci-archive:path:tag
55 An image tag in a directory compliant with "Open Container Image Lay‐
56 out Specification" at path.

58
59 DEPENDENCIES
60 Buildah resolves the path to the registry to pull from by using the
61 /etc/containers/registries.conf file, containers-registries.conf(5).
62 If the buildah pull command fails with an "image not known" error,
63 first verify that the registries.conf file is installed and configured
64 appropriately.
65
66
68 The image ID of the image that was pulled. On error 1 is returned.
69
70
72 --all-tags, a
73
74
75 All tagged images in the repository will be pulled.
76
77
78 --authfile path
79
80
81 Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/contain‐
82 ers/auth.json, which is set using buildah login. If the authorization
83 state is not found there, $HOME/.docker/config.json is checked, which
84 is set using docker login.
85
86
87 --cert-dir path
88
89
90 Use certificates at path (*.crt, *.cert, *.key) to connect to the reg‐
91 istry. The default certificates directory is /etc/containers/certs.d.
92
93
94 --creds creds
95
96
97 The [username[:password]] to use to authenticate with the registry if
98 required. If one or both values are not supplied, a command line
99 prompt will appear and the value can be entered. The password is
100 entered without echo.
101
102
103 --quiet, -q
104
105
106 If an image needs to be pulled from the registry, suppress progress
107 output.
108
109
110 --remove-signatures
111
112
113 Don't copy signatures when pulling images.
114
115
116 --shm-size=""
117
118
119 Size of /dev/shm. The format is <number><unit>. number must be greater
120 than 0. Unit is optional and can be b (bytes), k (kilobytes),
121 m(megabytes), or g (gigabytes). If you omit the unit, the system uses
122 bytes. If you omit the size entirely, the system uses 64m.
123
124
125 --tls-verify bool-value
126
127
128 Require HTTPS and verify certificates when talking to container reg‐
129 istries (defaults to true)

164 BUILD_REGISTRY_SOURCES
165
166
167 BUILD_REGISTRY_SOURCES, if set, is treated as a JSON object which con‐
168 tains lists of registry names under the keys insecureRegistries,
169 blockedRegistries, and allowedRegistries.
170
171
172 When pulling an image from a registry, if the name of the registry
173 matches any of the items in the blockedRegistries list, the image pull
174 attempt is denied. If there are registries in the allowedRegistries
175 list, and the registry's name is not in the list, the pull attempt is
176 denied.
177
178
179 TMPDIR The TMPDIR environment variable allows the user to specify where
180 temporary files are stored while pulling and pushing images. Defaults
181 to '/var/tmp'.
182
183
185 registries.conf (/etc/containers/registries.conf)
186
187
188 registries.conf is the configuration file which specifies which con‐
189 tainer registries should be consulted when completing image names which
190 do not include a registry or domain portion.
191
192
193 policy.json (/etc/containers/policy.json)
194
195
196 Signature policy file. This defines the trust policy for container
197 images. Controls which container registries can be used for image, and
198 whether or not the tool should trust the images.
