Helm Install
helm install
install a chart
Synopsis
This command installs a chart archive.
The install argument must be a chart reference, a path to a packaged chart, a path to an unpacked chart directory or a URL.
To override values in a chart, use either the '--values' flag and pass in a file or use the '--set' flag and pass configuration from the command line, to force a string value use '--set-string'. You can use '--set-file' to set individual values from a file when the value itself is too long for the command line or is dynamically generated. You can also use '--set-json' to set json values (scalars/objects/arrays) from the command line.
$ helm install -f myvalues.yaml myredis ./redis
or
$ helm install --set name=prod myredis ./redis
or
$ helm install --set-string long_int=1234567890 myredis ./redis
or
$ helm install --set-file my_script=dothings.sh myredis ./redis
or
$ helm install --set-json 'master.sidecars=[{"name":"sidecar","image":"myImage","imagePullPolicy":"Always","ports":[{"name":"portname","containerPort":1234}]}]' myredis ./redis
You can specify the '--values'/'-f' flag multiple times. The priority will be given to the last (right-most) file specified. For example, if both myvalues.yaml and override.yaml contained a key called 'Test', the value set in override.yaml would take precedence:
$ helm install -f myvalues.yaml -f override.yaml myredis ./redis
You can specify the '--set' flag multiple times. The priority will be given to the last (right-most) set specified. For example, if both 'bar' and 'newbar' values are set for a key called 'foo', the 'newbar' value would take precedence:
$ helm install --set foo=bar --set foo=newbar myredis ./redis
Similarly, in the following example 'foo' is set to '["four"]':
$ helm install --set-json='foo=["one", "two", "three"]' --set-json='foo=["four"]' myredis ./redis
And in the following example, 'foo' is set to '{"key1":"value1","key2":"bar"}':
$ helm install --set-json='foo={"key1":"value1","key2":"value2"}' --set-json='foo.key2="bar"' myredis ./redis
To check the generated manifests of a release without installing the chart, the --debug and --dry-run flags can be combined.
The --dry-run flag will output all generated chart manifests, including Secrets which can contain sensitive values. To hide Kubernetes Secrets use the --hide-secret flag. Please carefully consider how and when these flags are used.
If --verify is set, the chart MUST have a provenance file, and the provenance file MUST pass all verification steps.
There are six different ways you can express the chart you want to install:
- By chart reference: helm install mymaria example/mariadb
- By path to a packaged chart: helm install mynginx ./nginx-1.2.3.tgz
- By path to an unpacked chart directory: helm install mynginx ./nginx
- By absolute URL: helm install mynginx https://example.com/charts/nginx-1.2.3.tgz
- By chart reference and repo url: helm install --repo https://example.com/charts/ mynginx nginx
- By OCI registries: helm install mynginx --version 1.2.3 oci://example.com/charts/nginx
CHART REFERENCES
A chart reference is a convenient way of referencing a chart in a chart repository.
When you use a chart reference with a repo prefix ('example/mariadb'), Helm will look in the local configuration for a chart repository named 'example', and will then look for a chart in that repository whose name is 'mariadb'. It will install the latest stable version of that chart until you specify '--devel' flag to also include development version (alpha, beta, and release candidate releases), or supply a version number with the '--version' flag.
To see the list of chart repositories, use 'helm repo list'. To search for charts in a repository, use 'helm search'.
helm install [NAME] [CHART] [flags]
Options
--atomic if set, the installation process deletes the installation on failure. The --wait flag will be set automatically if --atomic is used
--ca-file string verify certificates of HTTPS-enabled servers using this CA bundle
--cert-file string identify HTTPS client using this SSL certificate file
--create-namespace create the release namespace if not present
--dependency-update update dependencies if they are missing before installing the chart
--description string add a custom description
--devel use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored
--disable-openapi-validation if set, the installation process will not validate rendered templates against the Kubernetes OpenAPI Schema
--dry-run string[="client"] simulate an install. If --dry-run is set with no option being specified or as '--dry-run=client', it will not attempt cluster connections. Setting '--dry-run=server' allows attempting cluster connections.
--enable-dns enable DNS lookups when rendering templates
--force force resource updates through a replacement strategy
-g, --generate-name generate the name (and omit the NAME parameter)
-h, --help help for install
--hide-notes if set, do not show notes in install output. Does not affect presence in chart metadata
--hide-secret hide Kubernetes Secrets when also using the --dry-run flag
--insecure-skip-tls-verify skip tls certificate checks for the chart download
--key-file string identify HTTPS client using this SSL key file
--keyring string location of public keys used for verification (default "~/.gnupg/pubring.gpg")
-l, --labels stringToString Labels that would be added to release metadata. Should be divided by comma. (default [])
--name-template string specify template used to name the release
--no-hooks prevent hooks from running during install
-o, --output format prints the output in the specified format. Allowed values: table, json, yaml (default table)
--pass-credentials pass credentials to all domains
--password string chart repository password where to locate the requested chart
--plain-http use insecure HTTP connections for the chart download
--post-renderer postRendererString the path to an executable to be used for post rendering. If it exists in $PATH, the binary will be used, otherwise it will try to look for the executable at the given path
--post-renderer-args postRendererArgsSlice an argument to the post-renderer (can specify multiple) (default [])
--render-subchart-notes if set, render subchart notes along with the parent
--replace re-use the given name, only if that name is a deleted release which remains in the history. This is unsafe in production
--repo string chart repository url where to locate the requested chart
--set stringArray set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
--set-file stringArray set values from respective files specified via the command line (can specify multiple or separate values with commas: key1=path1,key2=path2)
--set-json stringArray set JSON values on the command line (can specify multiple or separate values with commas: key1=jsonval1,key2=jsonval2)
--set-literal stringArray set a literal STRING value on the command line
--set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
--skip-crds if set, no CRDs will be installed. By default, CRDs are installed if not already present
--skip-schema-validation if set, disables JSON schema validation
--timeout duration time to wait for any individual Kubernetes operation (like Jobs for hooks) (default 5m0s)
--username string chart repository username where to locate the requested chart
-f, --values strings specify values in a YAML file or a URL (can specify multiple)
--verify verify the package before using it
--version string specify a version constraint for the chart version to use. This constraint can be a specific tag (e.g. 1.1.1) or it may reference a valid range (e.g. ^2.0.0). If this is not specified, the latest version is used
--wait if set, will wait until all Pods, PVCs, Services, and minimum number of Pods of a Deployment, StatefulSet, or ReplicaSet are in a ready state before marking the release as successful. It will wait for as long as --timeout
--wait-for-jobs if set and --wait enabled, will wait until all Jobs have been completed before marking the release as successful. It will wait for as long as --timeout
Options inherited from parent commands
--burst-limit int client-side default throttling limit (default 100)
--debug enable verbose output
--kube-apiserver string the address and the port for the Kubernetes API server
--kube-as-group stringArray group to impersonate for the operation, this flag can be repeated to specify multiple groups.
--kube-as-user string username to impersonate for the operation
