| + | First, if you just need to see less output, you can have docker only show you the more recent lines: | ||
| + | <code>docker logs --since 30s -f <container_name_or_id></code> | ||
| + | Or you can put a number of lines to limit: | ||

| + | - ''Exec'' a command, for example sh, into the container id. | ||
| + | - ''Ps'' the id if required. | ||
| + | - ''Kill'' the id. | ||
| + | <code> | ||

| + | ===== Shortcuts ===== | ||
| + | Imaginemos que tienes un Dockerfile sin **CMD** definido, podrías construir el contenedor con: | ||
| + | <code> | ||
| + | docker build -f Dockerfile.svn -t svn . | ||
| + | </code> | ||
| + | Y luego correr dentro de él con: | ||
| + | <code> | ||
| + | docker run -ti svn sh | ||
