tomsweeneyredhat 7ddac33de9 [v4.4.1-rhel] [CI:DOCS] Touch up secret man page 
This is a working theory fix.  The man pages including the
secret.md option are not resolving properly.  The secret.md
file is the only one with a text line with three back ticks on the start
and end of the line.  Elsewhere we have the backticks on separate lines
and the text in it's own line.

This might not fix the issue, but at the very least it makes things
consistent.

--secret=secret[,opt=opt ...]

Give the container access to a secret. Can be specified multiple times.

A secret is a blob of sensitive data which a container needs at runtime but should not be stored in the image or in source control, such as usernames and passwords, TLS certificates and keys, SSH keys or other important generic strings or binary content (up to 500 kb in size).

When secrets are specified as type mount, the secrets are copied and mounted into the container when a container is created. When secrets are specified as type env, the secret will be set as an environment variable within the container. Secrets are written in the container at the time of container creation, and modifying the secret using podman secret commands after the container is created will not affect the secret inside the container.

Secrets and its storage are managed using the podman secret command.

Secret Options

  • type=mount|env : How the secret will be exposed to the container. mount mounts the secret into the container as a file. env exposes the secret as a environment variable. Defaults to mount.
  • target=target : Target of secret. For mounted secrets, this is the path to the secret inside the container. If a fully qualified path is provided, the secret will be mounted at that location. Otherwise, the secret will be mounted to /run/secrets/target. If target is not set, by default the secret will be mounted to /run/secrets/secretname. For env secrets, this is the environment variable key. Defaults to secretname.
  • uid=0 : UID of secret. Defaults to 0. Mount secret type only.
  • gid=0 : GID of secret. Defaults to 0. Mount secret type only.
  • mode=0 : Mode of secret. Defaults to 0444. Mount secret type only.

Examples

Mount at /my/location/mysecret with UID 1.

--secret mysecret,target=/my/location/mysecret,uid=1

Mount at /run/secrets/customtarget with mode 0777.

--secret mysecret,target=customtarget,mode=0777

Create a secret environment variable called ENVSEC.

--secret mysecret,type=env,target=ENVSEC
