# Set, Get, And Unset Env Vars With Dokku
|
|
|
|
The `dokku` CLI provides `config` subcommands for managing environment variables
|
|
for the target container.
|
|
|
|
An env var can be set for an active container with `config:set`:
|
|
|
|
```bash
|
|
$ dokku config:set app-name JEMALLOC_ENABLED=true MALLOC_CONF="stats_print:true"
|
|
```
|
|
|
|
Notice I'm able to set multiple env vars at once if needed.
|
|
|
|
If I ever need to check what an env var is currently set to for one of my app
|
|
containers, I can use `config:get`:
|
|
|
|
```bash
|
|
$ dokku config:get app-name JEMALLOC_ENABLED
|
|
true
|
|
```
|
|
|
|
I can always override any value with another `config:set`. However, if I need to
|
|
entirely remove the env var, I can use `config:unset`:
|
|
|
|
```bash
|
|
$ dokku config:unset app-name MALLOC_CONF
|
|
```
|
