How create container with arrow

Question

Tikzpicture

I have graph and small group. Trouble is. How create arrow from container AND from objects to objects?

Answer 1

• image is out of context, so some parameters/options for image's elemets can be only guessed
• you tagged question with luatex, is there some problem related to it?

• arrows on above image are defined by join=by -Stealth and by \draw[-Stealth] (node i) to ["opis"] (node j)

mwe for above image:

\documentclass[ tikz, border=3mm]{standalone}
%---------------------------------------------------------------%
\usetikzlibrary{arrows.meta, chains, fit, positioning, quotes}

\begin{document}
    \begin{tikzpicture}[
node distance = 5mm and 7mm,
  start chain = A going above,
  base/.style = {rectangle, draw, rounded corners,
                 minimum width=24mm, minimum height=8mm},
 inbox/.style = {base, fill=blue!20, on chain, join=by -Stealth},
outbox/.style = {base, fill=red!20},
                    ]
\node [inbox]   {3};    % node name = A-1
\node [inbox]   {2};
\node [inbox]   {1};    %             A-3
\node (f)       [base, fit=(A-1) (A-3)] {};
\node (test)    [outbox, above=of f]    {Test};
%
\draw[-Stealth] (f) to ["opis" ']    (test);
    \end{tikzpicture}
\end{document}

short explanation of mwe code:

• for all nodes is defined base style, which contain common node shapes features. it is latter used for define specific nodes in picture

• for inner nodes (1, 2 and 3) is for placing used chains library. it put nodes in chain with distance between them determined by node distance = .... since chain is named (A) nodes are automatically named as A-1, A-2 and A-3

• use of chains also enable macro join which simplified drawing connection lines between nodes in chain. style of connection can be determined locally (as is done in above mwe) or you can define external and this style also use for other lines in picture
• around inner nodes is node "f" (as fit ..., but you can choose any name you liked), which fit them, i.e. it enclose all nodes between given coordinates. for this is used library fit which draw node's shape around specified nodes or coordinates. in your case this is obtained by fit=(A-1) (A-3) where (A-1) and (A-3) are names of the most outer nodes in the chain
• for connection between f and start node is used arrows to which is add label "opis" (description? :) ). for it is used quotes library an+d syntax ["..."] which works only if for drawing line is used to or edge and not at --.
• for more details about tikz please read "TikZ & PGF manual for version 3.0.1a. it is part of pgf installation in your computer. it is stored in "... \doc\generic\pgf\pgfmanual.pdf". manual is hige (over 1150 pages), but for start is sufucient to read tutorials and part III TikZ ist kein Zeichenprogramm

Answer 2

\documentclass[twocolumn]{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{fit,arrows.meta}
\tikzset{%
 >={Latex[width=2mm,length=2mm]},
 base/.style = {rectangle, rounded corners, thick,
               minimum width=2em, minimum height=1em,
               node distance=6em, text centered, font=\sffamily},
}
\tikzset{jeden/.style={draw, fill=gray!15,node distance=6em}}
\tikzset{dwa/.style={ draw, rounded corners}}

\begin{document}
This is a text.
\tikzstyle{ramka} = [rectangle, draw, inner sep=0.5cm, dashed]
\begin{center}
\vskip 1mm
\begin{tikzpicture}[scale=.9, transform shape]
\node [jeden] (zero)  at  (0, 0)    {Test 0};
\node [dwa,right of=zero,name=one,node distance=9em] (one) {1};
\node [dwa,below of=one,node distance=4em] (two) {2};
\node [dwa,below of=two] (three) {3};
\node [dwa,below of=three,minimum width=7em] (four) {4};

\node [ramka, fit=(two) (four)] (container) {};

\draw [->] (one) -- (zero);
\draw [->] (container) -- node[text width=2cm,near end] {opis} (one);
\draw [->] (three) -- (two);
\draw [->] (four) -- (three);
\end{tikzpicture}
\end{center}
End off message. End of text.
\end{document}

I add some modifications to show different distance. but base style not good
